Bone Marrow Adipogenesis Is Affected by Insulin-Like Growth Factor-1 Complexes

Fat tissue, which is composed of lipid-filled adipocytes that accumulate during aging, displaces mineralized tissue and reduces the mechanical integrity bone. Bone marrow adipocytes provide stroma for maintenance of mesencymal stem cells (MSC) and reside at sites of bone turnover (i.e., endosteal surfaces where osteoblasts form new bone), potentially influencing cell activity via a paracrine route.
