A natural protein fragment may not just slow scarring — it may help tissue heal back

Scarring inside organs, called fibrosis, quietly drives many serious diseases, and today's treatments mostly slow it down. A peer-reviewed study in the Journal of Biological Chemistry describes a candidate built from a natural protein fragment that, in lab research, pushed scar-forming cells toward a restorative state instead. It is early, pre-clinical work, but it points at reversal rather than delay.
