Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation. 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 (mesenchyme), while endochondral ossification involves cartilage as a precursor.

WebbOsteoblasts The formation of bone matrix on bone-forming surfaces has been well studied. The osteoblast is derived from an as yet to be identified precursor stem cell of mesenchymal origin and in cell culture behaves similarly to fibroblasts, except for its ability to form mineralized matrix. Webb8 juni 2024 · The osteoblast, the bone cell responsible for forming new bone, is found in the growing portions of bone, including the periosteum and endosteum. Osteoblasts, which do not divide, synthesize and secrete the collagen matrix and calcium salts. As the secreted matrix surrounding the osteoblast calcifies, the osteoblast becomes trapped within it.
