29.1 Introduction

Osteoblasts and osteoclasts are located in bone, a natural nanostructured-mineralized organic matrix. While osteoblasts make bone, osteoclasts decompose bone by releasing acid that degrades calcium phosphate-based apatite minerals into an aqueous environment. The synthesis, deposition, ...
