Stem cell treatment & Dilated cardiomyopathy

Written based on 26 research studies on PubMed, searched on 14 Nov 2026.

The claim

Posts online say that stem cell treatment helps with dilated cardiomyopathy.

Where research stands

We found 107 published papers on stem cell treatment and dilated cardiomyopathy. They were published between 2002 and 2026. 6 of them are studies in people. 4 of them compared people who got it with a group that did not. 16 were studies in animals, and 39 were only in cells in the lab. 29 papers are reviews that sum up other studies. 3 new studies in people are running or will start soon, say the trial registers. 20 research projects on stem cell treatment for dilated cardiomyopathy are funded and still running.
