WebChondrocytes are the cells responsible for cartilage formation (see Figure 25.1). In addition to the mechanical role of articular cartilage in the joints, cartilage is critical for bone development in the process of endochondral ossification. During this process, a cartilaginous template is formed and then replaced by bone tissue. Web24 jul. 2024 · Biology definition: Chondroblasts refer to any of the perichondrial cells involved in the formation of chondrocytes and ECM of the cartilage. Etymology: Greek “khondros” (cartilage) and “blastos” (germ). Synonyms: subchondral cortico-spongious progenitors; perichondrial cells; chondroplast. Figure 2: Chondroblasts of cartilage.

The plate's chondrocytes are under constant division by mitosis. These daughter cells stack facing the epiphysis while the older cells are pushed towards the diaphysis. As the older chondrocytes degenerate, osteoblasts ossify the remains to form new bone.
