First seen Apr 16, 2026 · Last updated Jun 21, 2026 · Updated 10 times
Summary
This early study tested whether injecting donor stem cells directly into the colon could help people with severe ulcerative colitis that didn't respond to standard treatments. Only 7 adults took part before the study was stopped early. The main goal was to check safety, and researchers also looked for signs of remission.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
remestemcel-L (stem cells from a donor's bone marrow)
What this could lead to
If it works, this could point toward a new way to control severe ulcerative colitis without surgery.
What could go wrong
This was a very small, early-phase trial that was terminated early, so results are limited. Stem cell treatments can have unknown long-term risks.
