Mouse Osteoblastic Cell Line (MC3T3-E1) Expresses Extracellular Calcium (Ca2+o)–Sensing Receptor and Its Agonists Stimulate Chemotaxis and Proliferation of MC3T3-E1 Cells

Abstract excerpt

The calcium-sensing receptor (CaR) is a G protein-coupled receptor that plays key roles in extracellular calcium ion (Ca2+o) homeostasis in parathyroid gland and kidney. Osteoblasts appear at sites of osteoclastic bone resorption during bone remodeling in the "reversal" phase following osteoclastic resorption and preceding bone formation. Bone resorption produces substantial local increases in Ca2+o that could...
