Clarifying the interplay between bone cells in bone remodeling

Osaka University study shows spatiotemporal intercellular interactions between mature osteoblasts and mature osteoclasts in bone homeostasis in vivo

Bone homeostasis is regulated by communication between bone-forming mature osteoblasts (mOB) and bone-resorptive mature osteoclasts (mOC). However, th...
