Scientists found that low serine levels spark a shift in hair stem cells, transforming them into wound-healing experts — with diet playing a possible role.
Rockefeller scientists uncovered how hair follicle stem cells can switch from growing hair to repairing skin when nutrients run low. The key lies in serine, an amino acid that activates a stress signal telling cells to conserve energy. When both injury and low serine occur, stem cells fully pivot to skin repair. The discovery could lead to dietary or medical ways to boost healing.
