Clastosome

Small nuclear bodies (0.2-0.5 m) described as donut shaped due to the peripheral capsule around these bodies. The first mention of clastosomes was made in 1960 by De Man et al. Clastosomes are not typically present in normal cells, making them hard to detect. They form under high proteolysis conditions within the nucleus and degrade once there is a decrease. Osmotic stress has also been shown to cause the formation of clastosomes.

The Clastosome would be an important addition to the ‘Cell Nucleus’ Wiki page because it plays a role in cell function. With further research, we may discover that this nuclear body has a more influential job in cell function than what is already known.
