Abstract: This invention describes methods for treating wound healing pathologies, inhibiting or reversing fibrotic skin disorders, including but not limited to keloids, atrophic and hypertrophic scars, and reversing skin aging via generating new dermal adipocytes (DAs). Methods described herein comprise (a) grafting of human hair follicles or (b) direct delivery of conditioned media from in vitro cultured hair follicles, or (c) delivery of purified individual factors secreted by hair follicles, or (d) delivery of small molecule agonists that mimic hair derived signaling activities, or (e) delivery of small molecule antagonists that inhibit anti-adipogenic programs, or (f) delivery of small molecule agonists of pro-adipogenic programs to convert endogenous wound or scar skin fibroblasts into new DAs.

Abstract: The invention provides compositions and methods to modulate hair growth in a tissue comprising administering to the tissue an effective amount of an agent that inhibits or augments Bone Morphogenic Protein (BMP) signaling in the tissue, thereby facilitating or inhibiting hair growth.
