How do osteocytes form
WebOsteocytes are formed from osteoblasts, and become part of the bone (and, as discussed above, ‘become’ osteocytes) when they mature. They send out long tendrils (as seen in the figure) which connect numerous osteocytes to each other. They produce bone matrix, including collagen and calcium/phosphorus compounds, that eventually covers them. WebOsteoblasts form a closely packed sheet on the surface of the bone, from which cellular processes extend through the developing bone. They arise from the differentiation of osteogenic cells in the periosteum, the tissue …

WebOssification, or osteogenesis, is the process of bone formation by osteoblasts. Ossification is distinct from the process of calcification; whereas calcification takes place during the ossification of bones, it can also occur in other tissues. Ossification begins approximately six weeks after fertilization in an embryo. WebJun 8, 2024 · Osteocytes are the longest living bone cell, making up 90–95% of cells in bone tissue in contrast to osteoclasts and osteoblasts making up ~5% (40). Residing within the lacuna of the mineralized bone matrix, osteocytes form dendritic processes that extend out from their cell bodies into spaces known as canaliculi.
