Rhabdomyosarcoma (RMS) is a pediatric soft tissue sarcoma that histologically resembles embryonic skeletal muscle. RMS occurs throughout the body and an exclusively myogenic origin does not account for RMS occurring in sites devoid of skeletal muscle. We previously described a RMS model activating a conditional constitutively active Smoothened mutant (SmoM2) with aP2-Cre. Using genetic fate mapping, we show SmoM2 expression in Cre expressing endothelial progenitors results in myogenic transdifferentiation and RMS. We illustrate endothelium and skeletal muscle within the head and neck arise from Kdr expressing progenitors and that hedgehog pathway activation results in aberrant expression of myogenic specification factors as a potential mechanism driving rhabdomyosarcomagenesis. These findings suggest that RMS can originate from aberrant development of non-myogenic cells. Using genetic fate mapping, Drummond et al. show that hedgehog pathway activation in endothelial progenitors results in aberrant expression of myogenic specification factors, myogenic transdifferentiation, and rhabdomyosarcoma (RMS). The finding may explain how RMS develops in sites devoid of skeletal muscle.
