WebApr 4, 2024 · OA is a heterogeneous disease characterized by progressive degeneration of articular cartilage combined with subchondral bone remodeling and synovial membrane inflammation ( Ruan et al., 2013 ). Aging, obesity, trauma, and mechanical loading are the main etiologic factors of OA ( Chen et al., 2024 ). WebDec 6, 2016 · Cell death in skeletal component cells, including chondrocytes, osteoblasts, and osteocytes, plays roles in skeletal development, maintenance, and repair as well as in the pathogenesis of osteoarthritis and osteoporosis. Chondrocyte proliferation, differentiation, and apoptosis are important steps for endochondral ossification.
WebJul 7, 2024 · Bone matrix secreted by the osteoblasts forms a bone collar. The bone collar prevents nutrients from reaching the hypertrophied chondrocytes, causing them to degenerate.

WebFeb 12, 2024 · In the embryo, cartilage gradually calcifies, and chondrocytes are replaced by bone cells, or osteocytes. After birth a thin plate of cartilage, called the epiphyseal plate, persists at the ends of growing bones, finally becoming ossified itself only when the bone behind it has completed its growth. WebCell biology. endochondral bone formation occurs with a cartilage model. chondrocytes produce cartilage which is absorbed by osteoclasts. osteoblasts lay down bone on cartilaginous framework (bone replaces cartilage, cartilage is not converted to bone) forms primary trabecular bone. bone deposition occurs on metaphyseal side.
WebJan 17, 2024 · This serves as support for the new bone. Chondrocytes in the primary center of ossification begin to grow (hypertrophy). They stop secreting collagen and other proteoglycans and begin secreting alkaline phosphatase, an enzyme essential for mineral deposition. Then calcification of the matrix occurs.
