An osteocytea star-shaped type of bone cellis the most commonly found cell in mature bone tissueand can live as long as the organism itself. They are derived from osteoprogenitor cells, some of which differentiate into active osteoblasts.

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.
