The claim
Posts online say that stem cell treatment helps with bronchiectasis.
Where research stands
We found 16 published papers on stem cell treatment and bronchiectasis. They were published between 2008 and 2026. 1 of them is a study in people. 1 of them compared people who got it with a group that did not. None was a study in animals, and none was only in cells in the lab. 2 papers are reviews that sum up other studies. 1 new study in people is running or will start soon, say the trial registers.
- 1In people1 with a comparison group

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 bronchiectasis.
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.
