Related terms: Stem Cell; Osteoblast; Osteoclast; Chondrocyte; Endochondral Here we have investigated intramembranous ossification during cranial bone development in mouse models of skeletal genetic diseases that exhibit craniofacial bone defects. On the contrary, endochondral ossification is dependent on a cartilage model. Intramembranous ossification is a process that forms flat bones such as the skull and the clavicle, through the remodelling of mesenchymal connective tissue. There are two processes resulting in the formation of normal, healthy bone tissue: Intramembranous ossification is the direct laying down of bone into the primitive connective tissue , while endochondral ossification involves cartilage as a precursor.
