How osteoblasts lay bone

Nettet28. okt. 2005 · During osteogenesis, osteoblasts lay down osteoid and transform into osteocytes embedded in mineralized bone matrix. Despite the fact that osteocytes are the most abundant cellular component of bone, little is known about the process of osteoblast-to-osteocyte transformation. NettetThis is very soft - and so the bone should be kept immobile. After a few weeks, the callus is stable enough for angiogenesis within it. Osteoblasts (at the periosteum) now lay down new bone matrix (collagen). This forms 'woven bone'. The soft callus is completely replaced by woven bone - called the HARD CALLUS (when it is mineralised).
