Where this comes from

Abstract

Wound healing in adult mammalian tissues generally involves scarring instead of tissue regeneration. A study in this issue of Cell reveals that after injury, reindeer antler skin regenerates by priming regenerative genes in wound fibroblasts instead of forming a scar through an inflammatory gene program.
