Summary

This study tests whether injections of stem cells from donated fat tissue can improve the quality of old burn scars. 39 adults with hypertrophic scars (at least 2 years old) will receive stem cells in one scar area and a placebo in another. The main goal is to see if patients report less pain, itching, and tightness, and if scars look and feel better.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
allogeneic adipose-derived mesenchymal stromal cells (stem cells from donated fat tissue)
What this could lead to
If it works, this could offer a new treatment to reduce pain, itching, and stiffness from burn scars, improving quality of life for survivors.
What could go wrong
This is an early phase 1/2 trial with only 39 people, so results may not apply to everyone. Stem cell treatments can have side effects like injection site reactions or unexpected immune responses.
