Dive into the fascinating world of osteocytes with this educational video. Osteocytes, the most abundant cells in bone tissue, play a crucial role in maintaining bone health and integrity. Discover their structure, function, and pivotal contributions to bone remodeling, fracture healing, and overall skeletal health. Explore how osteocytes communicate within bone tissue and orchestrate the dynamic balance between bone formation (osteoblasts) and resorption (osteoclasts). Whether you're a student, educator, or simply curious about the complexities of bone biology, this video provides an insightful journey into the world of osteocytes.

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
