Bone metabolism study using osteoblasts and osteoclasts

Study Overview

Bone structure and strength are maintained through a balance between bone formation by osteoblasts and bone resorption by osteoclasts.
This study will examine the effects of test substances on osteoblast and osteoclast differentiation, with the aim of verifying functional substances that support bone health and searching for new substances.
