During these processes, hypertrophic conversion and calcification of chondrocytes (the late-phase differentiation) is a crucial process of chondrogenic differentiation. Indian hedgehog (Ihh), a secreted protein expressed in early hypertrophic chondrocytes, is thought to be involved in regulation of hypertrophic conversion via a feedback loop through the perichondrium. In the present study, we showed by Northern analysis and in situ hybridization that Smoothened (Smo), a key component in hedgehog signal transduction, was expressed in chondrocytes in both adult mice and mouse embryos at 16 days post-coitum in vivo, suggesting that Ihh directly acts on chondrocytes. We previously reported that Ihh, Patched and Smo were all expressed in differentiated ATDC5 cells. Exogenously administered mouse recombinant N-terminal protein of Ihh (mrIhh-N) upregulated the gene expression of type X collagen, a phenotypic marker of hypertrophic chondrocytes, as well as osteoprotegerin ligand (OPGL), a potent stimulator of osteoclastogenesis and osteoclast activity, while it did not modulate the expression of Ihh itself, bone morphogenetic protein (BMP)-4, BMP-6, transforming growth factor (TGF)-beta1 and TGF-beta2 in differentiated ATDC5 cells. Moreover, when added to the osteoclast cultures, mrIhh-N markedly stimulated the formation of resorption pits on dentine slices. Our data support the hypothesis that Ihh stimulated the late-phase chondrogenic differentiation in differentiated ATDC5 cells and upregulated the gene expression of OPGL in these cells."xsd:string |
