Research Abstract

Bone cells exhibit dynamic changes in their morphologies and differentiate from cuboidal osteoblasts into stellate osteocytes with dendritic processes. Detailed state of the dendritic network is yet to be elucidated. Therefore in this study, we clarified a part of osteocyte functions by capturing osteocyte network and function in bone of mice, a commonly used model-animal, and also by comparing mice with another species.
