Résumé
Two genetic diseases, Gorlin syndrome and McCune-Albright syndrome (MAS), show completely opposite symptoms in terms of bone mineral density and hedgehog (Hh) activity. In this study, we utilized human induced pluripotent stem cell (iPSC)-based models of the two diseases to understand the roles of Hh signaling in osteogenesis. Gorlin syndrome-derived iPSCs showed increased osteoblastogenesis and mineralization with Hh signaling activation and upregulation of a set of transcription factors in an osteogenic culture, compared with the isogenic control. MAS-specific iPSCs showed poor mineralization with low Hh signaling activity in the osteogenic culture; impaired osteoblastogenesis was restored to the normal level by treatment with an Hh signaling-activating small molecule. These data suggest that Hh signaling is a key controller for differentiation of osteoblasts from precursors. This study may pave a path to new drug therapies for genetic abnormalities in calcification caused by dysregulation of Hh signaling.
