F.A.Q
What Are Stem Cells?
By Dr. Yoly Castellanos | Date: AGO 20 2024
Stem cells are special cells that have the ability to transform into other types of cells in the body, such as bone, muscle, cartilage, or skin cells. Additionally, they have the ability to self-renew, meaning they can divide and produce more stem cells.
In regenerative medicine, stem cells are extremely valuable because they help repair and regenerate damaged tissues, reduce inflammation, and support the immune system.
There are different types of stem cells; for example, mesenchymal stem cells (MSCs) from the umbilical cord, which are young and highly versatile. These are frequently used in treatments because they have a low risk of rejection and are effective in treating chronic and degenerative conditions. These are the ones we at OmniStem use.
Key Characteristics of U-MSCs
Differentiation Capacity: U-MSCs can transform into different cell types, including osteocytes (bone cells), chondrocytes (cartilage cells), and adipocytes (fat cells), among others.
Immunomodulatory Properties: They can modulate the immune response, which is useful in treating autoimmune diseases and preventing transplant rejection.
Regenerative Ability: These cells can aid in the repair and regeneration of damaged tissues, making them promising for treating injuries and degenerative diseases.
Accessibility and Ethics: Umbilical cord stem cells are relatively easy to obtain from an umbilical cord that would otherwise be discarded after birth. Their collection does not pose significant ethical concerns, unlike embryonic stem cells.
These characteristics make U-MSCs a valuable resource in the research and treatment of a wide range of medical conditions, including neurological, cardiac, orthopedic, and autoimmune diseases.
What Are Exosomes?
By Dr. Yoly Castellanos | Date: AGO 19 2024
Exosomes are microscopic, sac-like vesicles naturally released by cells, containing a rich payload of proteins, RNA, and other biomolecules essential for cellular communication and repair. Typically 30–200 nanometers in size, these extracellular vesicles play a pivotal role in maintaining and restoring cellular health.
At OmniStem, we harness the therapeutic potential of exosomes derived from umbilical cord mesenchymal stem cells (U-MSCs). These exosomes act as messengers, delivering regenerative signals to damaged tissues to support healing and reduce inflammation.
Key Roles of Exosomes
Cell-to-Cell Communication: Exosomes facilitate the transfer of biological information, enabling coordinated responses across cells.
Immune Modulation: They influence the immune system, helping balance inflammation and repair.
Regenerative Applications: Exosomes are central to treatments for skin rejuvenation, hair restoration, and advanced regenerative therapies.
Diagnostic Potential: Their contents reflect the state of their cell of origin, making them valuable tools for early detection and monitoring of conditions like cancer.
Exosomes are found in U-MSC, and their ability to reflect their originating cells makes them a promising focus for both research and clinical innovation. At OmniStem, we leverage this science to enhance the outcomes of our regenerative medicine therapies.

The Roles of U-MSCs and Exosomes
By Dr. Yoly Castellanos | Date: AGO 19 2024
Umbilical cord-derived mesenchymal stem cells (U-MSCs) are a type of adult stem cell harvested from Wharton’s jelly, a cell-rich tissue within the umbilical cord. These young, undifferentiated cells are multipotent, allowing them to transform into various tissue types, such as bone, cartilage, muscle, and fat.
This versatility makes them invaluable in regenerative medicine, where they play essential roles in tissue repair, inflammation reduction, and immune modulation. Containing natural growth factors, anti-inflammatory molecules, and signaling proteins, U-MSCs are effective in repairing damaged tissues and restoring immune balance, particularly in chronic or degenerative conditions.
Their low risk of rejection and inherent immunomodulatory properties make U-MSCs a safe, effective choice for reducing inflammation and promoting healing across a broad range of therapeutic applications.
Exosomes Derived from U-MSCs
Exosomes are nano-sized vesicles (30–150 nanometers) naturally secreted by U-MSCs. These cell-free particles carry bioactive molecules, including proteins, RNA, lipids, and growth factors, which function as intercellular messengers, delivering instructions that influence cellular behavior.
Unlike complete stem cells, exosomes work mainly through cell-to-cell communication instead of differentiation, enabling them to activate tissue repair, reduce inflammation, and enhance immune modulation throughout the body.
Their small size allows them lo to cross biological barriers, such as the blood-brain and nasal barriers, delivering therapeutic signals directly to target cells. This capability makes them highly effective in treating neurodegenerative diseases and modulating immune responses without the risks associated with cell-based therapies. Additionally, exosomes’ precision in targeting specific areas optimizes the body’s regenerative response, reduces immune rejection risk, and promotes anti-inflammatory healing.
Why We Use Both U-MSCs and Exosomes
Combining U-MSCs and their exosomes leverages the unique strengths of each. While U-MSCs offer direct regenerative capabilities through cell replacement and tissue repair, exosomes enhance cellular function, reduce inflammation, and promote healing without requiring full cell transplantation.
Together, U-MSCs and exosomes create a powerful, holistic approach to regenerative care, addressing both the underlying tissue damage and inflammation with precise, targeted healing.
Key Differences Between U-MSCs and Their Exosomes
Characteristic
U-MSCs
U-MSCs Derived Exosomes
Source
Derived from Wharton’s jelly in the umbilical cord, an ethically sourced, rich source of mesenchymal stem cells without harming the donor.
Nano-sized vesicles secreted by U-MSCs, carrying molecular cargo such as proteins, lipids, RNA, and growth factors.
Structure
Complete, nucleated cells with cellular organelles (e.g., mitochondria, nucleus, endoplasmic reticulum) for metabolic and regenerative functions.
Small, membrane-bound vesicles (30–150 nm) lacking organelles or nucleus, acting as messengers with bioactive molecules.
Differentiation Ability
Multipotent, able to differentiate into various cell types such as bone, cartilage, muscle, and fat cells, allowing them to directly replace damaged cells.
Do not differentiate; exert therapeutic effects by signaling to resident cells, promoting healing and functional improvement.
Mechanism of Action
Integrate and proliferate within damaged tissue, differentiating into target cell types to replace or restore damaged tissues. U-MSCs also release bioactive molecules.
Facilitate intercellular communication by delivering signaling molecules directly into target cells, modulating cellular environment.
Immunomodulatory Properties
Release cytokines and growth factors that suppress pro-inflammatory responses, reduce immune cell activation, and promote T-regulatory cell growth to prevent autoimmunity.
Contain immunomodulatory molecules (e.g., anti-inflammatory cytokines, miRNAs) that interact with immune cells, reducing inflammation.
Therapeutic Applications
Effective for tissue repair and regeneration, such as in osteoarthritis, spinal conditions, and sports injuries. Ideal for conditions requiring new tissue generation.
Ideal for conditions needing immune modulation, anti-inflammatory effects, or neural protection, including neurological, autoimmune, and dermatological conditions.
Administration Methods
Typically administered intravenously or directly into target tissues (e.g., intra-articular injections for joints) to allow migration to the injury site.
Can be administered intravenously, intranasally (to reach the brain), ocularly, or in localized injections (e.g., facial skin) for targeted, high-absorption effects.

Can be administered intravenously, intranasally (to reach the brain), ocularly, or in localized injections (e.g., facial skin) for targeted, high-absorption effects.
Blood-Brain Barrier Penetration
Limited ability to cross the BBB, restricting direct treatment of CNS diseases; their use in neurological conditions is limited to areas outside this barrier.
Known to cross the BBB, making them effective for neurological applications like Alzheimer’s, Parkinson’s, and other neurodegenerative diseases.
Main Benefits
Direct tissue regeneration and repair through differentiation into specific cell types; potent anti-inflammatory properties beneficial in joint and tissue repair.
Facilitate cell signaling for enhanced tissue healing, anti-inflammatory effects, neuroprotection, skin rejuvenation, and immune regulation.
Tissue Targeting and Longevity
Can actively migrate to inflammation or injury sites; however, long-term presence depends on immune compatibility and may face rejection if not well-matched.
More versatile in tissue targeting due to their small size, with minimal immune reactions, leading to potentially longer activity in the target tissue.
Tumorigenic Risk
No known risk of uncontrolled cell growth or tumor formation; no chromosomal abnormalities, ensuring cell safety.
No tumorigenic risk, as exosomes cannot proliferate; they only influence existing cells and are rapidly metabolized, presenting a low-risk profile for cancer patients.
Anti-Aging and Aesthetic Use
Beneficial for age-related musculoskeletal decline, such as arthritis and osteoporosis, due to their regenerative capacity.
Widely used in anti-aging and cosmetic treatments (e.g., skin rejuvenation, hair growth) due to collagen stimulation and cellular renewal without invasive procedures.
Conclusion
Umbilical cord-derived mesenchymal stem cells (U-MSCs) and their exosomes offer complementary advantages in regenerative medicine. By combining the direct tissue repair abilities of U-MSCs with the targeted anti-inflammatory and signaling effects of exosomes.

How are our U-MSC and derived exosomes sourced?
At OmniStem we source our umbilical cord mesenchymal stem cells and U-MSC derived exosomes through a collaborative partnership with the National University in Medellín, Colombia. We work closely with a skilled team of biotechnologists and a fertility clinic, which provides us with donated umbilical cords.
The harvesting and preservation of umbilical cord mesenchymal stem cells (U-MSCs) is a delicate and highly technical procedure carried out in three phases to ensure the viability and effectiveness of the cells for therapeutic applications.
Suitability
This stage involves a comprehensive evaluation of umbilical cord donors, which includes DNA and laboratory analyses to ensure the integrity and viability of the U-MSC stem cells obtained.
Harvesting and Preservation
This phase emphasizes the collection and preservation of the umbilical cord, typically discarded postpartum and the extraction and laboratory expansion of multipotent cells and their derived exosomes.
Expansion and Testing
The stem cells used for therapeutic applications are verified by a third party lab and expanded in our laboratory, in this phase we process the extraction the U-MSC derived exosomes.
Our team in Colombia produces some of the highest-quality biologics available globally. While similar work is conducted in countries like South Korea, China, and Russia, our focus is distinct in emphasizing both exosome and mesenchymal U-MSC therapies.
Our Signature Protocols
Umbilical cord mesenchymal stem cell (U-MSC) and derived exosome therapies are the cornerstone of regenerative medicine, offering a new treatment approach for various medical conditions and diseases where treatment options are limited.
The use of biological products derived from U-MSC obtained from Wharton's gelatin (mesenchymal cells and exosomes derived from the umbilical cord) improve organ function, exert immunomodulatory effects, repair, regenerate and anti-inflammatory effect of affected tissues in the entire system, while exhibiting an exemplary safety profile.
The StemSpine® protocol targets injured vertebral structures by directly applying biologics derived from umbilical cord mesenchymal stem cells (U-MSCs). This approach aims to deliver immunomodulatory, reparative, regenerative, and anti-inflammatory effects to the affected areas, such as intervertebral discs or vertebrae, enhancing healing and improving spine conditions.
Joint injections entail the targeted application of biologics derived from U-MSC stem cells to injured joints. The biological product is deposited directly at the site of the injury (such as the tendon, joint, or joint capsule), enabling immunomodulatory, reparative, regenerative, and anti-inflammatory effects.
The Stem Grow treatment targets both halting hair loss and enhancing the quality and thickness of the hair. Utilizing biological products derived from U-MSC, it aims to regenerate hair, counteract pathological mechanisms contributing to hair loss, and stimulate damaged hair follicles. This treatment entails the subdermal application of exosomes to the scalp.
Is This Therapy Available in the U.S.?
U-MSC-derived allogenic stem cell therapies are currently not allowed in the U.S.
While mesenchymal stem cells (U-MSCs) have received FDA approval, the FDA does not permit the expansion of allogenic stem cells. As a result, patients undergoing these therapies in the U.S. typically receive a limited number of cells, which may reduce the potential benefits, including the use of U-MSC-derived exosomes.
At OmniStem, we use a safe and controlled laboratory process to expand these cells, enabling us to administer tens of millions of U-MSCs and U-MSC exosomes to our patients. This approach significantly enhances treatment outcomes.
This is a key reason many individuals travel to countries like Colombia, Panama, Mexico, and the Dominican Republic to seek recognized providers of the most advanced regenerative medicine biologics available.

HBOT's current indications in illnesses like as wound healing, thermal or radiation burns, and tissue necrosis point to its function in facilitating the regeneration process. Various research has revealed that HBOT plays a function in vascularization, angiogenesis, and collagen production augmentation. Individual regeneration capacity is influenced by both environmental and genetic factors. Furthermore, the regenerating ability of different types of tissues varies, and this ability declines with age. HBOT affects physiological processes at the genetic level by altering gene expression, delaying cell senescence, and assisting in telomere length enhancement. The positive results in a variety of indications, ranging from tissue regeneration to better cognitive function, indicate that it has enormous potential in regenerative and anti-aging therapy.},

The aim of this study was to compare RA with OA, evaluating their redox status and the effects of ozone on their clinical response to combined therapy with ozone. The redox status of 80 patients was determined: antioxidant defenses, injury markers, two subjective variables (pain and disability), and levels of antibodies against cyclic citrullinated peptides were evaluated. Oxidative stress and clinical response to combined therapy with ozone was higher than in the case of RA. After medical ozone treatment, there was an increase in antioxidant defense and a decrease in injury markers as well as pain, disability, and autoantibody concentrations. Redox biomarkers were able to differentiate between both arthritic diseases and combined therapy with ozone (methotrexate + ozone), showing a therapeutic selectivity for RA in comparison with OA.},

Ozonated blood allows for the use of ozone in a safe modality, as plasma and blood cells are endowed with an antioxidant system able to quench ozone’s pro-oxidant property and to elicit the Nrf2/Kwap1/ARE pathway. Methods. We present two clinical studies, a case-series (six patients) observational study adopting ozone as a major autohemotherapy and topical ozone to address infected post-surgical wounds with multi-drug resistant bacteria and an observational study (250 patients) using ozonated blood for treating knee osteoarthritis. Results. Ozonated blood via major autohemotherapy reduced the extent of infections in wounds, reduced the inflammatory biomarkers by more than 75% and improved patients’ QoL, whereas ozonated blood via minor autohemotherapy improved significantly (p < 0.001) WOMAC and Lequesne’s parameters in knee osteoarthritis. Conclusions. The models described, i.e., ozone autohemotherapy in wound antimicrobial treatment and ozonated blood in knee osteoarthrosis, following our protocols, share the outstanding ability of ozone to modulate the innate immune response and address bacterial clearance as well as inflammation and pain.},

IVDD occurs as a result of aging, mechanical trauma, lifestyle factors, and certain genetic abnormalities, leads to loss of nucleus pulposus, alteration in the composition of the extracellular matrix, excessive oxidative stress, and inflammation in the intervertebral disc. Pharmacological and surgical interventions are considered a boon for the treatment of IVDD, but the effectiveness of those strategies is limited. Mesenchymal stem cells (MSCs) have recently emerged as a possible promising regenerative therapy for IVDD due to their paracrine effect, restoration of the degenerated cells, and capacity for differentiation into disc cells. Recent investigations have shown that the pleiotropic effect of MSCs is not related to differentiation capacity but is mediated by the secretion of soluble paracrine factors. Early studies have demonstrated that MSC-derived exosomes have therapeutic potential for treating IVDD by promoting cell proliferation, tissue regeneration, modulation of the inflammatory response, and reduced apoptosis. This paper highlights the current state of MSC-derived exosomes in the field of treatment of IVDD with further possible future developments, applications, and challenges.},

Despite the clinical outcomes of the surgical procedures being satisfactory, the repair of the rotator cuff remains problematic, such as through failure of healing, adhesion formation, and fatty infiltration. Stem cells have high proliferation, strong paracrine action, and multiple differentiation potential, which promote tendon remodeling and fibrocartilage formation and increase biomechanical strength. Additionally, stem cell-derived extracellular vesicles (EVs) can increase collagen synthesis and inhibit inflammation and adhesion formation by carrying regulatory proteins and microRNAs. Therefore, stem cell-based therapy is a promising therapeutic strategy that has great potential for rotator cuff healing. In this review, we summarize the advances of stem cells and stem cell-derived EVs in rotator cuff repair and highlight the underlying mechanism of stem cells and stem cell-derived EVs and biomaterial delivery systems.

abstract = {Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus is a highly contagious microorganism, and despite substantial investigation, no progress has been achieved in treating post-COVID complications. However, the virus has made various mutations and has spread around the world. Researchers have tried different treatments to reduce the side effects of the COVID-19 symptoms. One of the most common and effective treatments now used is steroid therapy to reduce the complications of this disease. Long-term steroid therapy for chronic inflammation following COVID-19 is harmful and increases the risk of secondary infection, and effective treatment remains challenging owing to fibrosis and severe inflammation and infection. Sometimes our immune system can severely damage ourselves in disease. In the past, many researchers have conducted various studies on the immunomodulatory properties of stem cells. This property of stem cells led them to modulate the immune system of autoimmune diseases like diabetes, multiple sclerosis, and Parkinson's. Because of their immunomodulatory properties, stem cell-based therapy employing mesenchymal or hematopoietic stem cells may be a viable alternative treatment option in some patients. By priming the immune system and providing cytokines, chemokines, and growth factors, stem cells can be employed to build a long-term regenerative and protective response. This review addresses the latest trends and rapid progress in stem cell treatment for Acute Respiratory Distress Syndrome (ARDS) following COVID-19.},

The primary endpoint was an altered proportion of whole-lung lesion volumes measured by high-resolution CT. Other imaging outcomes, 6 min walking distance (6-MWD), lung function, plasma biomarkers, and adverse events were also recorded and analyzed. This trial was registered with ClinicalTrials.gov (NCT04288102).
Findings
MSC administration improved in whole-lung lesion volume compared with the placebo with a difference of −10.8% (95% CI: −20.7%, −1.5%, p = 0.030) on day 10. MSC also reduced the proportion of solid component lesion volume compared with the placebo at each follow-up point. More interestingly, 17.9% (10/56) of patients in the MSC group had normal CT images at month 12, but none in the placebo group (p = 0.013). The incidence of symptoms was lower in the MSC group than in the placebo group at each follow-up time. Neutralizing antibodies were all positive, with a similar median inhibition rate (61.6% vs. 67.6%) in both groups at month 12. No difference in adverse events at the 1-year follow-up and tumor markers at month 12 were observed between the two groups.},

abstract = {The severe acute respiratory syndrome coronavirus 2 has led to the worldwide pandemic named coronavirus disease 2019 (COVID-19). It has caused a significant increase in the number of cases and mortalities since its first diagnosis in December 2019. Although COVID-19 primarily affects the respiratory system, neurological involvement of the central and peripheral nervous system has been also reported. Herein, the higher risk of neurodegenerative diseases in COVID-19 patients in future is also imaginable. Neurological complications of COVID-19 infection are more commonly seen in severely ill individuals; but, earlier diagnosis and treatment can lead to better long-lasting results. In this respect, stem cell biotechnologies with considerable self-renewal and differentiation capacities have experienced great progress in the field of neurological disorders whether in finding out their underlying processes or proving them promising therapeutic approaches. Herein, many neurological disorders have been found to benefit from stem cell medicine strategies. Accordingly, in the present review, the authors are trying to discuss stem cell-based biotechnologies as promising therapeutic options for neurological disorders secondary to COVID-19 infection through reviewing neurological manifestations of COVID-19 and current stem cell-based biotechnologies for neurological disorders.},

abstract = {Senescent endothelial cells (ECs) could impair the integrity of the blood vessel endothelium, leading to vascular aging and a series of diseases, such as atherosclerosis, diabetes. Preventing or mitigating EC senescence might serve as a promising therapeutic paradigm for these diseases. Recent studies showed that small extracellular vesicles (sEV) have the potential to transfer bioactive molecules into recipient cells and induce phenotypic changes. Since mesenchymal stem cells (MSCs) have long been postulated as an important source cell in regenerative medicine, herein we investigated the role and mechanism of MSC-derived sEV (MSC-sEV) on EC senescence. In vitro results showed that MSC-sEV reduced senescent biomarkers, decreased senescence-associated secretory phenotype (SASP), rescued angiogenesis, migration and other dysfunctions in senescent EC induced by oxidative stress. In the In vivo natural aging and type-2 diabetes mouse wound-healing models (both of which have senescent ECs), MSC-sEV promoted wound closure and new blood vessel formation. Mechanically, miRNA microarray showed that miR-146a was highly expressed in MSC-sEV and also upregulated in EC after MSC-sEV treatment. miR-146a inhibitors abolished the stimulatory effects of MSC-sEV on senescence. Moreover, we found miR-146a could suppress Src phosphorylation and downstream targets VE-cadherin and Caveolin-1. Collectively, our data indicate that MSC-sEV mitigated endothelial cell senescence and stimulate angiogenesis through miR-146a/Src.},

abstract = {The estimated cost of acute injuries in college-level sports in the USA is ∼1.5 billion dollars annually, without considering the cost of follow-up rehabilitation. In addition to this huge financial burden, sports injuries may be career-ending for some athletes without appropriate diagnosis and relevant interventions. With a growing number of females participating in contact-based and pivoting sports, middle-aged individuals returning to sports,s and natural injuries of aging all increasing, such costs and negative implications for quality of life will expand. For those injuries that cannot be predicted and prevented, there is a real need to optimize repair, recovery, and function post-injury in the sporting and clinical worlds. The 21st century has seen rapid growth in regenerative medicine for sporting injuries to progress recovery and facilitate return to sport. Such interventions harness knowledge relating to stem cells as a potential for injury repair.

Degeneration of the IVD occurs naturally with age, but mechanical trauma, lifestyle factors and certain genetic abnormalities can increase the likelihood of symptomatic disease progression. IVDD, often referred to as degenerative disc disease (DDD), poses an increasingly substantial financial burden due to the aging population and increasing incidence of obesity in the United States. Current treatments for IVDD include pharmacological and surgical interventions, but these lack the ability to stop the progression of disease and restore the functionality of the IVD. Biological therapies have been evaluated but show varying degrees of efficacy in reversing disc degeneration long-term. Stem cell-based therapies have shown promising results in the regeneration of the IVD, but face both biological and ethical limitations. Exosomes play an important role in intercellular communication, and stem cell-derived exosomes have been shown to maintain the therapeutic benefit of their origin cells without the associated risks. This review highlights the current state of research on the use of stem-cell derived exosomes in the treatment of IVDD.},

This process can be devastating physically and psychologically. Nevertheless, the available treatment strategies are limited, and the therapeutic outcomes are not satisfactory. According to the possible pathogenesis of nonscarring alopecia, especially androgenetic alopecia, recovering or replenishing the signals responsible for hair follicle stem cells activation is a promising strategy for hair regeneration. Recently, stem cell-based therapies, especially those based on the stem cell-derived conditioned medium (CM), which is secreted by stem cells and is rich in paracrine factors, have been widely explored as the hair regenerative medicine. Several studies have focused on altering the composition and up-regulating the amount of secretome of the stem cells, thereby enhancing its therapeutic effects. Besides, stem cell-derived exosomes, which are present in the CM as message entities, are also promising for hair regrowth. In this review, the up-to-date progress of research efforts focused on stem cell-based therapies for hair regeneration will be discussed, including their therapeutic potentials with respective merits and demerits, as well as the possible mechanisms.},

Frecuently Asked Questions
Empowering Patients Through Knowledge: This FAQ section is designed to provide clear and concise answers to the most common questions, covering everything from the fundamentals of stem cell therapy to the specifics of our treatments and protocols.
Regenerative Medicine
Regenerative medicine is a field of medicine that focuses on developing therapies that can help the body regenerate and repair damaged or diseased tissues and organs. This is achieved by using various types of cells, including stem cells, to help stimulate the body's natural healing processes.
Regenerative medicine uses stem cells, which have the ability to differentiate into different cell types, such as nerve cells, muscle cells, and blood cells, among others. These cells can be sourced from various places in the body, such as bone marrow, adipose tissue, or the umbilical of a live birth.
The goal of regenerative medicine is to develop therapies that can treat a wide range of conditions, including injuries, genetic disorders, and degenerative diseases, such as osteoarthritis, Alzheimer's disease, and heart disease, among others.
The potential of regenerative medicine is still being explored, but it offers promising opportunities to develop new treatments and improve patient outcomes.
Mesenchymal stem cells, derived from the umbilical cord of a live birth (U-MSC), serve as a potent repair system in the body.
These cells have the ability to divide and create an optimal environment for tissue repair, modulate immune responses, and reduce inflammation. U-MSC stem cells effectively target areas of degeneration, building, repairing, and growing new tissue.
Umbilical cord-derived mesenchymal stem cells are currently the most potent biologic available in the field of regenerative medicine.
Umbilical cord-derived stem-cell exosomes (U-MSC Exosomes) are tiny vesicles released by U-MSCs and are approximately 1000 times smaller than the mesenchymal stem cells from which they originate. These exosomes are packed with bioactive molecules that act as messengers between cells.
These lipid-lined nano vesicles carry potent anti-inflammatory, immunomodulatory, and regenerative signals to damaged tissues and organs, facilitating intercellular communication throughout the body.
This capability places U-MSC exosomes at the forefront of regenerative medicine, making them a crucial component in enhancing clinical outcomes for many medical conditions.
Stem cells are living cells with the capacity to self-renew and differentiate into various cell types. This ability allows them to repair and regenerate damaged tissues, making them powerful tools in regenerative medicine. Stem cells have a nucleus, enabling them to replicate and participate in long-term tissue regeneration by transforming into different cell types.
Exosomes, on the other hand, are not cells but extracellular vesicles produced and secreted by stem cells, among others. They are significantly smaller than stem cells (roughly 100 times smaller) and lack a nucleus. Exosomes act as messengers, delivering bioactive molecules such as proteins, RNA, and growth factors to other cells. Though they cannot replicate, exosomes are critical for enhancing communication between cells, modulating inflammation, and promoting tissue healing.
In essence, while stem cells provide a direct source of new cells for regeneration, exosomes facilitate healing by enhancing cellular communication and guiding repair processes.
At Omni-Stem, we specialize in the use of umbilical cord mesenchymal stem cells (U-MSCs), a type of perinatal stem cell. These cells are harvested from the umbilical cord tissue, which is a rich source of regenerative cells. U-MSCs share the broad differentiation potential and low immunogenicity characteristic of perinatal stem cells, making them less likely to provoke an immune response in recipients.
The advantages of using U-MSCs include their ease of collection and the non-invasive nature of their sourcing, which involves no harm to the mother or newborn. Umbilical cord mesenchymal stem cells are increasingly being recognized and utilized for their significant therapeutic potential in regenerative medicine, without the ethical concerns associated with embryonic stem cells.
At Omni-Stem we source our umbilical cord mesenchymal stem cells and U-MSC derived exosomes through a collaborative partnership with the National University in Medellín, Colombia. We work closely with a skilled team of biotechnologists and a fertility clinic, which provides us with donated umbilical cords. The harvesting and preservation of umbilical cord mesenchymal stem cells (U-MSCs) is a delicate and highly technical procedure carried out in three phases to ensure the viability and effectiveness of the cells for therapeutic applications:
Donor Suitability
This stage involves a comprehensive evaluation of umbilical cord donors, which includes DNA and laboratory analyses to ensure the integrity and viability of the U-MSC stem cells obtained.
Harvesting and Preservation
This phase emphasizes the collection and preservation of the umbilical cord, typically discarded postpartum and the extraction and laboratory expansion of multipotent cells and their derived exosomes.
Expansion and Testing
The stem cells used for therapeutic applications are verified by a third party lab and expanded in our laboratory, in this phase we process the extraction of the U-MSC derived exosomes.
Our team in Colombia produces some of the highest-quality biologics available globally. While similar work is conducted in countries like South Korea, China, and Russia, our focus is distinct in emphasizing both exosome and mesenchymal U-MSC therapies.
The preparation required before U-MSC (mesenchymal stem cell) therapy can vary depending on the specific treatment protocol and your medical condition. However, there are some general guidelines typically followed to ensure the best possible outcome of the therapy, including medical review, hydration, and lifestyle modifications. It is crucial to follow the specific instructions provided by our medical team regarding any preparations necessary for U-MSC stem cell therapy.
U-MSC Mesenchymal stem cells have received FDA approval, making these therapies accessible in the U.S. However, the FDA does not permit the expansion of allogenic stem cells.
Consequently, patients undergoing these therapies in the U.S. typically receive only a limited number of cells, missing out on the potential benefits of U-MSC derived exosomes.
We employ a safe and controlled process in our laboratory to expand these cells, allowing us to administer tens of millions of U-MSCs as well U-MSC Exosomes to patients, which significantly enhances treatment outcomes.
This is a key reason many individuals travel to Colombia to seek advance Regenerative Medicine treatments at OmniStem.
Treatments Procedures
Most of our protocols typically take about 1 hour with minimal downtime. However, considering that a patient care plan may involve multiple procedures, the entire process, including onboarding, treatment, and medical supervision, can take up to 4 days.`
The age restrictions for U-MSC (umbilical cord mesenchymal stem cell) therapy can vary depending on the specific treatment protocol and the patient's medical condition. Generally, there is no maximum age limit for MSC therapy as long as the patient is healthy enough and deemed a suitable candidate.
Like any medical treatment, MSC (mesenchymal stem cell) therapy may have some risks and potential complications. The specific risks and side effects of MSC therapy can vary depending on the patient's medical condition, the specific treatment protocol, and individual response to the therapy. It is important to discuss the potential risks and benefits of MSC therapy with a qualified healthcare professional before undergoing the treatment. Your healthcare professional will help you weigh the potential risks against the benefits and determine if MSC therapy is appropriate for your medical condition. They will also monitor you closely during and after the treatment to minimize the risk of complications and to ensure the best possible outcome.
U-MSC stem cell treatments are considered specialized and are generally not covered by insurance plans.
The duration of the effects of MSC (mesenchymal stem cell) therapy can vary depending on various factors, including the specific medical condition being treated, the type of stem cell therapy used, and the individual patient's response to the treatment. In some cases, patients may experience long-lasting or permanent improvements in their symptoms after undergoing MSC therapy. For example, in some patients with osteoarthritis, MSC therapy has improved joint pain and function that can last for several years.
However, in other cases, the effects of MSC therapy may be more temporary, and patients may require repeat treatments to maintain their benefits. For example, in patients with autoimmune conditions such as multiple sclerosis, MSC therapy may provide temporary relief from symptoms, but the effects may gradually diminish over time.
The specific eligibility criteria for regenerative MSC (mesenchymal stem cell) therapy can vary depending on the patient's medical condition, the specific treatment protocol, and the stem cell provider's guidelines. However, here are some general factors that may make you a good candidate for MSC therapy:
You have a medical condition that may benefit from regenerative therapy: MSC therapy may be appropriate for various medical conditions, including orthopedic injuries, neurological disorders, autoimmune diseases, and more. Your healthcare professional can help determine if your medical condition is appropriate for MSC therapy.
You have tried other treatments without success: U-MSC therapy may be appropriate if you have tried others without success or if those treatments have not provided sufficient relief from your symptoms.
You are in good overall health: U-MSC therapy may not be appropriate for patients with certain underlying health conditions or risk factors, such as a weakened immune system, a history of cancer, or a history of blood clotting disorders. Your healthcare professional will evaluate your overall health to determine if you are a suitable candidate for MSC therapy.
You are willing to commit to the treatment process: MSC therapy typically involves multiple injections or infusions over weeks or months. It is important to be willing and able to commit to the treatment process to achieve the best possible outcomes.
It is important to consult with a qualified healthcare professional to determine if MSC therapy is appropriate for your specific medical condition and to discuss any eligibility criteria or concerns you may have. Your healthcare professional can help guide you through the treatment process and provide personalized recommendations based on your needs and medical history.
The combination of regenerative stem cell therapy with other treatments or medications will depend on your specific medical condition and the advice of your healthcare professional. In some cases, it may be safe and appropriate to combine MSC (mesenchymal stem cell) therapy with other treatments or medications to achieve the best possible outcome.
For example, MSC therapy may be combined with physical therapy or anti-inflammatory medications to help manage pain and improve function in orthopedic injuries. In neurological disorders, MSC therapy may be combined with medications or other therapies to help improve cognitive function or reduce symptoms. However, it is important to inform your healthcare professional of all medications, supplements, or other treatments you are currently using before undergoing MSC therapy. Some medications or treatments may interact with the stem cells or interfere with the therapeutic effects of MSC therapy.
Additionally, it is important to follow your healthcare professional's advice and guidance regarding any adjustments to your current treatment plan or medications. Your healthcare professional can help determine if MSC therapy is appropriate in combination with other treatments or medications and provide personalized recommendations based on your individual needs and medical history.
The timeline for seeing results from U-MSC (mesenchymal stem cell) therapy can vary depending on the specific medical condition, the type of stem cell therapy used, and the individual patient's response to the treatment. In some cases, patients may notice improvements in their symptoms within a few weeks of starting MSC therapy, while in other cases, it may take several months or longer to see results. It is important to remember that MSC therapy is not a magic bullet and may not work for everyone. MSC therapy aims to help promote healing and regeneration within the body, but the extent and duration of the therapeutic effects can vary from patient to patient.
Your healthcare professional can provide personalized guidance on what to expect from U-MSC therapy based on your medical condition and treatment plan. They can also monitor your progress and adjust your treatment plan as needed to help optimize your outcomes.
Overall, OmniStem is committed to providing its patients and the broader community with educational resources that can help them make informed decisions about their healthcare and understand the potential benefits of U-MSC therapy.
