Stem-cell therapy: separating the 15% with real evidence from the 85% that's marketing

Stem-cell therapy is the most over-marketed medical category online. About 15% of the applications we see enquiries about have real evidence. The other 85% range from unproven to actively harmful. Here's our filter.

Applications with solid evidence

• Hematopoietic stem cell transplant (HSCT, also called bone marrow transplant) — for leukemia, lymphoma, aplastic anemia, sickle cell, thalassemia, and specific inherited metabolic disorders. Decades of data, well-regulated.
• Corneal stem-cell transplant — for specific corneal injuries. Limited but real evidence base.
• Research-grade trials — for specific diseases (multiple sclerosis, type-1 diabetes, certain cardiac conditions). Must be IRB-approved clinical trials, not "compassionate use" privately.

Applications where evidence is preliminary or mixed

Knee osteoarthritis (some small RCTs showing modest benefit, much longer-term data needed), certain autoimmune conditions (MS mostly in research settings), heart failure (mixed trial results). These may work but shouldn't be paid for outside clinical trials.

Applications where evidence is absent or refuted

Autism. ALS. Parkinson's. Cerebral palsy. Anti-aging. Erectile dysfunction. Hair regrowth. If a clinic is advertising stem cells for these, they're selling you something that doesn't work — regardless of the testimonials on their website.

How to evaluate a specific programme

• What condition and what cell source? (Autologous bone-marrow, adipose, umbilical cord — different quality regulations.)
• What's the supporting clinical evidence? If the centre points to testimonials or "patient stories," that's a red flag. Ask for published peer-reviewed data.
• Is the treatment regulated by the destination's health authority (FDA, EMA, CDSCO, etc.)? Unregulated clinics offer "stem-cell therapy" as a non-drug intervention; this is a workaround, not a feature.
• What's the follow-up protocol? Real programmes track outcomes systematically. Sketchy ones don't.

Destinations

For HSCT specifically: India (Tata Medical, CMC Vellore, HCG), Germany, South Korea, Singapore. For legitimate stem-cell research trials, it's usually academic medical centres in Germany, UK, US, or Japan — not standalone "stem cell clinics." Any programme operating out of a clinic that isn't attached to a hospital and doesn't have a published patient outcomes registry is worth walking away from.
