research Hair follicle micro-particle skin grafting induces scar remodeling via PI3K-AKT signaling: a randomized clinical trial
This study found that hair follicle micro-graft transplantation significantly improved scar remodeling outcomes in 40 patients, with greater reductions in scar volume, lower scar scores, and enhanced skin characteristics compared to punch excision alone, potentially due to activation of the PI3K-AKT pathway.
