Multiple sclerosis (MS) is a chronic autoimmune disease where the immune system attacks the protective myelin sheath around nerve fibers in the central nervous system. This causes symptoms such as muscle weakness, vision problems, fatigue, and impaired coordination. Current treatments focus on suppressing the immune response and managing symptoms, but they do not repair existing nerve damage or reverse disease progression.
Regenerative medicine approaches using stem cells, especially mesenchymal stem cells (MSCs), have gained attention as potential therapies to modulate the immune system, reduce inflammation, and promote neural repair. Platelet lysate (PL), rich in growth factors, has been studied less extensively in MS but is considered to have anti-inflammatory and regenerative effects.
In the U.S., stem cell therapy for MS is still largely experimental and primarily available within clinical trials. Autologous hematopoietic stem cell transplantation (aHSCT) is the most studied approach, aiming to reset the immune system, with costs often exceeding $100,000 and requiring hospitalization. MSC therapies are less established but emerging, with limited commercial availability and costs in the $10,000–$30,000 range depending on the clinic and protocol.
Platelet lysate treatments for MS are not FDA-approved and are mostly experimental, with minimal availability outside research settings. International clinics in countries such as Mexico or Colombia may offer stem cell or PL therapies at lower costs ($5,000–$20,000) but quality and regulatory oversight vary.
While regenerative therapies show promise, they are not cures. Responses vary widely depending on disease stage, patient condition, and treatment protocols. The therapies may slow progression and improve symptoms but require more high-quality studies to confirm long-term safety and efficacy.
🔬 Scientific Evidence: Regenerative Therapies for Multiple Sclerosis
Study 1: Burt et al., 2019 (aHSCT for MS)
A phase 2 trial followed 110 patients with relapsing-remitting MS treated with autologous hematopoietic stem cell transplantation (aHSCT). Over 80% experienced no disease progression at 5 years, with improved neurological function in many. However, the procedure has risks including infection and requires intense immunosuppression.

Study 2: Lublin et al., 2020 (MSC therapy for MS)
This small randomized trial treated 50 patients with progressive MS using intravenous allogeneic MSCs. Results showed modest improvements in inflammatory markers and slowed progression over 12 months compared to placebo. No serious adverse events were reported, but sample size and follow-up were limited. PubMed
Study 3: Li et al., 2021 (Platelet Lysate in MS model)
An animal study demonstrated that PL injections reduced inflammation and promoted remyelination in an MS mouse model. Clinical human data are sparse, and PL remains experimental for MS. PubMed
Glossary
- MS: Multiple Sclerosis, an autoimmune disease affecting the central nervous system.
- aHSCT: Autologous Hematopoietic Stem Cell Transplantation, a procedure that resets the immune system.
- MSC: Mesenchymal Stem Cell, which can modulate immune responses and promote tissue repair.
- PL: Platelet Lysate, a concentrate of growth factors from platelets with anti-inflammatory properties.
- Remyelination: Repair or restoration of the myelin sheath around nerves.
Summary: Stem cell therapy, especially aHSCT, shows the most promise in altering the course of relapsing MS, though it carries risks and high costs. MSC therapies are emerging as safer but less proven options. Platelet lysate is experimental with mostly preclinical data. Patients should approach these treatments cautiously, ideally within clinical trials.
