| Research Abstract |
To confirm the involvement of nerves for bone formation were examined for altered expression of the receptor of neuropeptides in the process to become osteoblasts from iPS cells. During three stage of cell differentiation; iPS, embryonic body, and osteoblast, the cells in iPS stage and early osteoblastic stage, the beta 2 adrenergic receptors and CGRP receptor were specifically expressed, and the NK-1 receptor is expressed specifically in the late differentiation of osteoblasts. These results suggest that neuropeptides affect the differentiation of osteoblast as the differentiation stage-dependent manner.
