Abstract
Bone develops either from endochondral or intramembranous ossification. Intramembranous ossification starts in condensed vascular connective tissue with differentiation of mesenchymal progenitor cells into bone forming osteoblasts. These osteoblasts proliferate around the branches of a capillary network forming incomplete layers of osteoblasts. Osteoblasts continue to secrete bone matrix that will first appear as thin strands or trabeculae. Then the bone matrix will be mineralized and osteoblasts will be trapped in the growing bone as osteocytes (Steiniche & Hauge, 2003; Sadler, 2010 and Snell, 2012).
