WebBone formation is an essential process in the development of the human body. It starts during the development of the foetus, and continues throughout childhood and … WebBone is formed in the embryo in two general ways. For most bones the general shape is first laid down as a cartilage model, which is then progressively replaced by bone (endochondral bone formation). A few bones (such as the clavicle and the calvarium) develop within a condensed region of fibrous tissue without a cartilaginous intermediate (membrane bone …

The steps include the following: Cartilage “model” of bone forms; this model continues to grow as ossification takes place. Ossification begins at a primary ossification center in the middle of the bone. WebResorption of bone matrix by the osteoclasts involves two steps: (1) dissolution of inorganic components (minerals), and (2) digestion of organic component of the bone matrix. ...

WebFurthermore, the paracrine regulation by PSCs of osteoclast formation was evaluated, using coculture, conditioned medium, and purified extracellular vesicles. Results showed that PSCs when mixed with autograft bone induce an increase in osteoblast:osteoclast ratio, promote bone matrix formation, and prevent bone graft resorption. WebLEARNING OBJECTIVE 7.
