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.Osteoblasts/osteocytes develop in mesenchyme.

In mature bones, osteocytes and their processes reside inside spaces called lacunae (Latin for a pit) and canaliculi, respectively. Osteocytes are simply osteoblasts trapped in the matrix that they secrete. They are networked to each other via long cytoplasmic extensions that occupy tiny canals called canaliculi, which are used for exchange of nutrients and waste through gap junctions.

Although osteocytes have reduced synthetic activity and (like osteoblasts) are not capable of mitotic division, they are actively involved in the routine turnover of bony matrix, through various mechanosensory mechanisms. They destroy bone through a rapid, transient (relative to osteoclasts) mechanism called osteocytic osteolysis. Hydroxyapatite, calcium carbonate and calcium phosphate is deposited around the cell
Embark on an exploration of osteocytes through the lens of histology in this enlightening video. Osteocytes, the primary cells of bone tissue, exhibit diverse forms and functions crucial to skeletal health. Delve into the intricate structures and roles of osteocytes, including their communication networks within bone matrix, involvement in bone remodeling processes, and response to mechanical stress. Learn about the various types of osteocytes and their specific adaptations, from maintaining bone density to participating in healing fractures. Whether you're a student, educator, or enthusiast of histology and anatomy, this video provides a comprehensive look into the cellular architecture of bone tissue and the vital role of osteocytes.
