Research Abstract

Little is known about the cellular behavior of osteoblasts and osteoclasts in bone tissue in vivo. To elucidate the mechanisms of the maintenance of bone homeostasis and the pathogenesis of bone diseases by visualization of the dynamics of bone remodeling in live bone tissues, we performed intravital two-photon imaging of osteoblasts and osteoclasts in the mouse calvarial bones in the physiological and pathological conditions such as osteoporosis.
