An osteocyte, a star-shaped type of bone cell, is the most commonly found cell in mature bone tissue, and can live as long as the organism itself. The adult human body has about 42 billion of them. Osteocytes do not divide and have an average half life of 25 years. They are derived from osteoprogenitor cells, some of which differentiate into active osteoblasts.


Osteocyte: Osteocyte, a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone. Osteocytes derive from osteoblasts, or bone-forming cells, and are essentially osteoblasts surrounded by the products they


Osteocytes also experience other constraints as a result of their site of residence. First, direct contact of osteocytes with other cells is limited to the tips of their processes and does not occur along extended cell-cell borders, as in tissues where cells are closely packed in two or three dimensions.


osteocyte [os´te-o-sīt″] an osteoblast that has become embedded within the bone matrix, occupying a bone lacuna, and sending, through the canaliculi, cytoplasmic processes that connect with other osteocytes in developing bone. os·te·o·cyte (os'tē-ō-sīt'), A cell of osseous tissue that occupies a lacuna and has cytoplasmic processes that extend ...


Osteocytes are located inside the bone and have a connection with each other and with other cells with the help of their long branches. Osteocytes are at the perfect position to sense any pressure or mechanical strain in the bone. It is estimated that osteocytes comprise about 95% of the total of cells of the bone.


The osteocytes direct osteoclasts to the site of the damage, hastening healing. Osteoclast. While osteoblasts and osteocytes have the same source, and are, in fact, different stages of the same cells, osteoclasts are derived from cells in the bone marrow. Osteoclasts perform the job of breaking down the composite material in bones, with the ...
