Are mesenchymal stem cells safe?
Yes. Multiple peer-reviewed studies confirm MSCs have an excellent safety profile. They carry no viral DNA, no cancer risk, and no rejection risk when properly sourced and quality-tested. The most common short-term effects are mild fatigue, a brief headache, or slight nausea - all transient and monitored by Dr. Capasso during treatment.
Will my body reject the stem cells?
No. Umbilical cord-derived MSCs are immune-privileged - they naturally evade the immune system's rejection response. They do not require HLA matching, blood type matching, or immunosuppressive drugs before or after treatment. This is one of the primary reasons UC-MSCs are preferred over bone marrow or fat-derived cells.
What is the difference between MSCs and Muse cells?
MSCs are multipotent - they can differentiate into a defined range of cell types. Muse cells are a rare subpopulation found within MSC populations that are truly pluripotent - capable of differentiating into cells from all three biological germ layers. Muse cells also have autonomous homing capability and are intrinsically non-tumorigenic, making them among the most advanced therapeutic stem cells available.
Can stem cells cause cancer or tumors?
Not with the cell types used at Regener8MD. Umbilical cord-derived MSCs have extremely low telomerase activity and no evidence of tumorigenicity in clinical studies. Muse cells are intrinsically non-tumorigenic - their biology actively suppresses oncogenic pathways through the let-7 microRNA mechanism. Embryonic stem cells and iPSCs carry teratoma risk; the cells used at Regener8MD do not.
How do stem cells know where to go in the body?
Damaged tissue releases a distress signal called sphingosine-1-phosphate (S1P). MSCs and Muse cells carry surface receptors (S1PR2) that detect this signal and cause them to migrate toward injury sites following IV administration. This autonomous homing mechanism is what makes IV delivery effective - the cells navigate to where repair is needed without surgical targeting.
Do stem cells get trapped in the lungs?
The "pulmonary first pass effect" is a documented phenomenon where some cell types lodge temporarily in pulmonary capillaries after IV administration. UC-MSCs at optimal size navigate this efficiently. Cells briefly present in lung tissue still exert therapeutic benefit through paracrine signaling, and the majority proceed to damaged tissue sites via the S1P homing mechanism.
Can stem cells help with aging?
Yes. Aging is fundamentally a process of accumulated cellular damage, chronic low-grade inflammation, and depleted regenerative capacity. MSC therapy addresses all three: replacing damaged cells, reducing systemic inflammation, and restoring the body's natural regenerative signaling. Patients consistently report improvements in energy, mental clarity, physical capacity, skin health, libido, and measurable reductions in biological age markers.
How long do the effects of stem cell therapy last?
Results vary by individual, condition, and lifestyle. Patients who maintain an active lifestyle, follow an anti-inflammatory diet, and minimize alcohol and tobacco see sustained benefits for 2–4+ years. Muse cell clinical trials have documented functional improvements maintained through 52-week follow-up periods. Dr. Capasso tracks your biomarkers continuously to measure and sustain the biological improvement.
Are the stem cells frozen? Does that affect quality?
Cells are cryogenically preserved at -150°F immediately after expansion - a standard protocol that maintains cell integrity without degrading therapeutic potency. Before every treatment, cells are carefully thawed and viability-tested to confirm they meet specification (minimum 80%, target 95%+). Treatment is not administered until Dr. Capasso confirms viability meets standard.
Are there ethical concerns with stem cell therapy?
Not with the approach used at Regener8MD. All cells are adult mesenchymal stem cells - not embryonic or fetal. They are ethically sourced from voluntarily donated, full-term human umbilical cords through AATB-certified suppliers. No embryos are used or harmed at any stage of the process.
Where do the donor cells come from?
All cells are sourced from voluntarily donated, full-term human umbilical cords through AATB-certified suppliers. Every donor undergoes comprehensive screening for HIV, hepatitis A/B/C/D, STDs, TB, Zika virus, HTLV 1 and 2, cancer history, autoimmune disease, chronic illness, and CJD. Cords from donors with any positive test result are rejected.
How is the quality of stem cells verified?
Every batch undergoes a comprehensive QC panel before treatment: sterility testing, mycoplasma PCR, endotoxin assay, karyotype analysis (confirms normal 46-chromosome composition), flow cytometry (confirms CD73, CD90, CD105 surface markers), potency testing (ATP cellular content), and cytokine secretion analysis. Cells must pass every test before Dr. Capasso approves their use.
Will I need more than one treatment?
Most patients see significant results from a single treatment protocol. Stem cell therapy is designed to produce long-term biological improvement - not monthly maintenance. Some patients choose to return as their biology evolves. Dr. Capasso tracks your biomarkers over time and advises based on what he sees in your data, not a predetermined schedule.
Is stem cell therapy right for me?
The first step is the Longevity Diagnostic Assessment - Dr. Capasso's comprehensive 180+ biomarker evaluation. He won't recommend a regenerative protocol until he's read your data. That assessment tells him which treatments your biology will respond to, what outcomes are realistic for your specific situation, and what to measure as you progress. That's the starting point for everyone at Regener8MD.
Can you use umbilical cord-derived stem cells instead of my own?
Yes. Umbilical cord-derived MSCs are available and have been widely used in regenerative medicine. However, Dr. Capasso's strong preference is to use your own stem cells whenever possible. With autologous MSCs, there is zero risk of your immune system rejecting the cells, no foreign DNA enters your body, and you can bank your cells for future use. Your banked stem cells are expanded in our laboratory and multiply over time, so they are always available for your next protocol - without requiring another harvest. For patients who are not good candidates for autologous harvest, UC-MSCs remain an excellent alternative, and Dr. Capasso will advise which approach is right for your specific case.
