A bone cell.

Osteocyte

 

the bone cell in vertebrate animals and man. Osteocytes are formed from osteoblasts in the development of bony tissue. They consist of cell bodies, which are embedded in the cavities of the intercellular substance of bone, while their long outgrowths are located in channels that extend from the cavities.

Osteonecrosis (ON), which involves the physiological remodeling of bone tissues [1], is thought to be caused by interruptions in blood flow, a decline in the function/number of osteoprogenitor cells, and apoptosis of the osteocytes [2-10].
