Indian hedgehog is an essential component of mechanotransduction complex to stimulate chondrocyte proliferation.


Indian hedgehog (Ihh), a member of the vertebrate hedgehog morphogen family, is a key signaling molecule that controls chondrocyte proliferation and differentiation. In this study, we show a novel function of Ihh. Namely, it acts as an essential mediator of mechanotransduction in cartilage. Cyclic mechanical stress greatly induces the expression of Ihh by… (More)
