What types of stem cell therapy are available for MS?
It is critical to understand that 'stem cell therapy for MS' refers to two very different treatments that are often confused:
| Treatment | What It Does | Evidence | Availability |
|---|---|---|---|
| HSCT (Hematopoietic SCT) | Resets the immune system using your own blood stem cells | Strongest — multiple RCTs | Select US academic centers + international |
| MSC Therapy (Mesenchymal SCs) | Anti-inflammatory, neuroprotective effects via IV infusion | Early-stage — phase 1/2 trials | Mostly international clinics |
Does HSCT work for MS?
HSCT has the strongest evidence of any stem cell treatment for any neurological condition. Multiple randomized controlled trials — including the landmark MIST trial — have shown HSCT is superior to disease-modifying drugs for relapsing-remitting MS in terms of halting disease progression and preventing new relapses. It is not a cure, but for the right patient (active RRMS, failed 2+ DMTs), it can produce long-term remission. It is a serious medical procedure with real risks and requires evaluation at a specialized center.
Does MSC therapy work for MS?
MSC therapy for MS is in earlier-stage development. Phase 1 and 2 trials have established safety and shown anti-inflammatory effects and some neurological improvement signals. It is not FDA-approved and is not available at US clinics outside of clinical trials. International clinics in Panama, Germany, Mexico, and Israel offer MSC protocols for MS. Patients with progressive MS who are not candidates for HSCT are the most common group seeking international MSC treatment.
