Matrix IGF-1 regulates bone mass by activation of mTOR in mesenchymal stem cells

Insulin-like growth factor 1 (IGF-1), the most abundant growth factor in the bone matrix, regulates bone mass in adulthood. We report that IGF-1 released from bone matrix stimulates osteoblastic differentiation of mesenchymal stem cell (MSCs) by activation of mTOR during bone remodeling. Mice knocko...
