This study showed that exosomes engineered to carry miR-29a, derived from adipose-derived mesenchymal stem cells, can reduce excessive scar formation. By delivering targeted molecular signals, these exosomes help skin heal with less scarring.

For patients concerned about scarring after surgery, injury, or burns, this research highlights an emerging precision regenerative therapy.
