The hair follicle dermal condensate is populated via migration, and the cells exhibit early changes in cell shape and cell cycle status; Fgf20 primes these cellular and molecular events.
Fibroblast growth factor (FGF) ligands exhibit different preferences for signaling cascades triggered through FGFR1, a receptor which is critical for skeletal development, and these differences likely contribute to the amazing complexity of developmental processes.
