Stem cell therapy is promoted for dozens of conditions, but the evidence differs enormously. For a few blood disorders it is an established, approved treatment. For most other conditions it is still being tested — or remains unproven. Use this page to see where each condition stands, then read the full guide.
How to read the evidence levels: Approved = an approved product or established treatment exists for specific uses · Promising = encouraging results in human trials, not yet proven · Early research = mostly small or early studies · Unproven = no convincing human benefit; avoid outside trials.
