The claim
Posts online say that stem cell treatment helps with aortic aneurysm.
Where research stands
We found 71 published papers on stem cell treatment and aortic aneurysm. They were published between 2006 and 2026. 1 of them is a study in people. 1 of them compared people who got it with a group that did not. 41 were studies in animals, and 10 were only in cells in the lab. 11 papers are reviews that sum up other studies. 1 new study in people is running or will start soon, say the trial registers. 3 research projects on stem cell treatment for aortic aneurysm are funded and still running.

What the studies found
We have not summed up these studies in words yet. The most important papers are listed under Sources.
Verdict
Stem cell treatment has been tested in randomised trials in people with aortic aneurysm.
What this means for you: A study in people is not proof that it helps you. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
