Evidence-Based Regenerative Medicine
Backed by Decades of Science and Research
At TurkeyStemcell, our treatment protocols are grounded in peer-reviewed research, internationally recognized standards, and continuously refined based on clinical outcomes.

What Are Stem Cells?
Inside the human body are hundreds of different types of cells that fulfill specific tasks and are responsible for maintaining its everyday function. Among these are stem cells, responsible for tissue repair and regeneration (also known as tissue remodeling) to maintain a healthy body.
Stem cells can self-renew by dividing to generate more stem cells of the same type. They can also differentiate into specialized cell types. Scientific evidence shows mesenchymal stem cells are safe and effective for supporting recovery and regeneration across a wide range of diseases and conditions.
Unlike most other cells, stem cells possess two key properties that make them uniquely valuable in medicine: self-renewal (the ability to divide and produce identical copies) and potency (the ability to differentiate into various specialized cell types such as bone, cartilage, muscle, and nerve cells). These properties underpin the entire field of regenerative medicine and cell therapy.
Types of Stem Cells Used in Medicine
While various stem cell types exist—embryonic stem cells, induced pluripotent stem cells (iPSCs), and adult stem cells—our clinic exclusively uses mesenchymal stem cells (MSCs) derived from ethically sourced umbilical cord tissue. Specifically, we use cells from the Wharton's jelly layer of the umbilical cord, which offers several advantages over other sources:
- No invasive harvesting procedure required from the patient
- Younger, more potent cells with higher proliferative capacity
- Lower immunogenicity, reducing the risk of rejection
- Greater paracrine signaling potential compared to bone marrow or adipose-derived MSCs
- Ethically sourced from donated umbilical cords after healthy full-term births

At TurkeyStemcell, We Use Wharton's Jelly-Derived Mesenchymal Stem Cells (WJ-MSCs)
Stem cells are adult/somatic cells that can be obtained from many different sources, such as bone marrow, adipose tissue, umbilical cords, and the placenta. We use umbilical cord-derived mesenchymal stem cells, specifically from the Wharton's jelly tissue (WJ-MSCs), as they are known to be among the most effective and have:
Exceptional Regenerative Properties
WJ-MSCs exhibit superior proliferative capacity and multi-lineage differentiation potential compared to bone marrow or adipose-derived alternatives.
Anti-Inflammatory Properties
Highly effective at reducing pro-inflammatory cytokines, increasing anti-inflammatory cytokines, and secreting exosomes that modulate the immune response.
Growth Factor Secretion
Release growth factors that stimulate tissue repair and regeneration of muscles, tendons, ligaments, discs, cartilage, and other areas.
Benefits of Wharton's Jelly Umbilical Cord-Derived MSCs
The use of WJ-MSCs has significant advantages over bone marrow or adipose-derived MSCs:
- Superior mesenchymal marker expression and modest pluripotency genes, which may confer better efficacy with greater safety
- Enhanced immunomodulatory profile, showing greater activity on lymphocytes through regulating different cell populations
- Reduced rejection risk — due to the absence of certain surface proteins (HLA class II), the patient's immune system does not consider these cells as foreign, significantly reducing the likelihood of adverse reactions
- No invasive harvesting — patients do not need to undergo additional procedures, as cells are sourced from donated umbilical cords
- Higher proliferative potential — allowing for greater cell expansion and higher dosing without loss of potency
Three Core Mechanisms of Action
Anti-Inflammatory & Angiogenesis
Through paracrine activity, MSCs release anti-inflammatory cytokines (IL-10, TGF-β, PGE2) and pro-angiogenic factors (VEGF, bFGF) that reduce inflammation and promote new blood vessel formation.
Cellular Repair & Stabilization
MSCs stabilize and repair damaged native cells through mitochondrial transfer and growth factor secretion, restoring cellular function at the site of injury.
Tissue Regeneration via Exosomes
MSCs secrete exosomes that signal the body's repair response, delivering regenerative cargo including miRNAs, proteins, and growth factors to damaged tissue.
Explore how these mechanisms are applied in our neurological, orthopedic, autoimmune, and autism support programs.
Allogeneic Therapies: No Invasive Harvesting Required
Our therapies are allogeneic, which means patients do not need to undergo extra invasive procedures to obtain stem cells. Our WJ-MSCs are sourced from donated umbilical cords collected after healthy, full-term births with full informed consent. Each umbilical cord is examined and analyzed in a clinical laboratory to ensure it is infection-free, then processed in our cell bank to isolate and purify only mesenchymal stem cells.
Our laboratory complies with widely accepted international standards, and our protocols have been designed based on extensive research into selecting, testing, refining, and purifying cells before they are cultured and expanded into infusions with the highest potential to stimulate healing.
Quality Control & Manufacturing Process
Screening
Although donors are pre-screened for health issues, the cells extracted from umbilical cords are tested for specific proteins and genes that research has identified offer high potential for effective treatment.
Purification
Cells that pass screening tests are purified and expanded so that therapy can be prepared containing millions of high-potency cells that the body can use to promote healing and reduce inflammation.
Ongoing Testing
Cells are tested as they are expanded and passaged into larger containers. Once expansion is complete, cells are tested again to verify purity, potency, viability (>95%), and sterility markers.
Cryo-Preservation
After cells have been expanded and tested, they are cryopreserved in our cell bank. When reactivated for treatment, they are tested once more to ensure quality and viability before administration.
Each cell product undergoes 12+ quality control tests including cell viability (>95% required), sterility testing, endotoxin screening, mycoplasma testing, identity verification via flow cytometry, karyotype analysis, and potency assays. This rigorous quality framework ensures consistent, safe, and effective cell products for every patient.
Hypoxia-Conditioned Mesenchymal Stem Cells
Preconditioning strategies to enhance the therapeutic function of MSCs in vitro include exposure to hypoxia, growth factors/cytokines, or conditioned medium. Mesenchymal stem cells have been demonstrated to be promising cell sources for therapeutic stem cell therapy due to their capability of tissue regeneration and immunomodulation.
Hypoxia, or exposure to a low-oxygen environment, is a preconditioning protocol to improve the therapeutic potential of MSCs. Recent studies report that MSCs cultured in a hypoxic environment may:
- Enhance the anti-inflammatory and migratory capacity of MSCs
- Improve angiogenic potency (new blood vessel formation)
- Increase cell survival and proliferation
- Reduce overall cell aging for improved protection and regeneration
The enhanced therapeutic effects of hypoxia-cultured MSCs have been validated in many clinical studies. Hypoxia-preconditioned MSCs have been successfully used to regenerate various musculoskeletal tissues, including cartilage, bone, and tendon, after injury and halt the progression of diseases.
At TurkeyStemcell, we offer advanced protocols using both hypoxic and normoxic MSCs in our treatment protocols. In both cases, we use Wharton's jelly umbilical cord-derived mesenchymal stem cells (WJ-MSC). Research shows both demonstrate exceptional anti-inflammatory properties, immune modulating capacity, and promote tissue repair and regeneration.
What Are MSC Exosomes?
Exosomes are a type of molecule secreted by MSCs — naturally occurring extracellular vesicles (30–150nm) found in all types of cells, including mesenchymal stem cells. They release anti-inflammatory cytokines, growth factors, and proteins to control inflammation and repair damaged cells.
MSC-derived exosomes carry a cargo of over 850 unique proteins, 150+ miRNAs, and various lipids and metabolites that can reprogram recipient cells toward regenerative phenotypes. Their nanoscale size allows them to cross biological barriers, including the blood-brain barrier, making them especially valuable for neurological conditions.
Exosomes act as signaling agents, influencing other cells in the body by releasing:
- Anti-inflammatory cytokines that modulate immune response
- Growth factors to promote healing and tissue regeneration
- Specific proteins that enhance cellular repair at the molecular level
Research demonstrates that adding exosomes helps enhance the speed and quality of tissue repair. This is why some patients receiving exosomes report more immediate relief of symptoms, with continued improvement until they experience the full benefits of the MSCs.
Exosomes are applied in the same manner and time as MSCs, so there are no additional procedures or injections required. At TurkeyStemcell, we isolate exosomes as we culture MSCs from umbilical cord tissue and concentrate them in our on-site laboratory to provide the highest possible potency.

Precision Stem Cell Applications
Our protocols precisely target treatment areas using advanced imaging technology and evidence-based delivery methods.
MSC therapy has been studied worldwide for more than 50 years. Research demonstrates the safety and efficacy of mesenchymal stem cell treatments and their regenerative and anti-inflammatory capacity in pathologies such as:
Administration Methods
Most patient protocols include at least one intravenous (IV) WJ-MSC infusion. For this simple procedure, cells are infused intravenously to allow them to circulate throughout the body. Other protocols include direct injection at specific treatment sites. When appropriate, our physicians use advanced imaging technology such as X-ray fluoroscopy and diagnostic ultrasound to guide cells to these sites precisely.
Intravenous (IV)
Systemic infusion allowing cells to circulate throughout the body and home to areas of inflammation.
Intra-articular
Direct injection into a joint, commonly used for arthritis and orthopedic injuries. Does not require sedation.
Intrathecal
Injection directly into the spinal canal, used for neurological conditions. Requires local anesthesia.
Intralesional
Injection directly into soft tissues at the site of damage or disease.
Intradiscal
Injection into discs and facets of the spine for degenerative disc disease. Requires sedation.
Intradermal
Injection into the dermal layer of the skin, used for aesthetic and anti-aging applications.
