Based on the fact that IR and IGF-1R are abundantly expressed in chondrocytes 27,28 and the previous work which showed upregulation of IR signaling in osteoblasts lacking IGF-1R, 12 we suspected that the increased proliferation of IR-deficient growth plate chondrocytes could be caused by upregulation of the IGF-1/IGF-1R signaling pathway

A health assessment matters
This effect was accompanied by a parallel accumulation of intracellular cAMP in ( B ) sAC +/+ caSMCs, but was lost in ( D ) sAC / caSMCs
