Osteocyte

Monday, July 23, 2012

An osteocyte is a mature bone tissue cell which originates from an osteoblast. It is star-shaped and is set in the bone calcified matrix. Osteocytes have cytoplasmatic processes which juts out away from the cell body through the canaliculi, which are tiny channels through which an osteocyte obtains nutrients and release its waste products. Although they can live a very long time, throughout the life of the individual, osteocytes sometimes suffer from apoptosis, which the programmed cell death, due to bone diseases, such as osteoarthritis.
