What is the success rate of stem cell therapy for Chronic Wounds & Ulcers?
A reliable success rate for wound cell or exosome therapy is not established. Partial area reduction, complete closure, time to closure, recurrence, infection and limb salvage are different endpoints and should not be merged. Wound size, perfusion, infection, pressure and metabolic control strongly affect outcome. The registered studies and their own prespecified endpoints are listed in the registry table on this page.
What the evidence shows for Chronic Wounds & Ulcers
Chronic-wound studies of cells and extracellular vesicles vary by wound cause, vascular status, infection, product, delivery, comparator and definition of closure. Treated-cohort percentages and historical controls cannot establish comparative efficacy. Wound-area reduction is not equivalent to durable complete closure, limb salvage or fewer infections. No pooled response rate is published here because the studies are too heterogeneous for a single figure to be meaningful. The registered studies and their own prespecified endpoints are listed in the registry table on this page.
