Submitter Supplied Information

Description
Hair follicle (HF) regeneration begins when communication between quiescent epithelial stem cells (SCs) and underlying mesenchymal dermal papillae (DP) generates sufficient activating cues to overcome repressive BMP signals from surrounding niche cells. We uncovered a hitherto unrecognized DP transmitter, TGF2, which activates Smad2/3 transiently in HFSCs concomitant with entry into tissue regeneration.
