Thread-grain transition of mitochondrial reticulum as a step of mitoptosis and apoptosis.

Association of mitochondrial population to a mitochondrial reticulum is typical of many types of the healthy cells. This allows the cell to organize a united intracellular power-transmitting system. However, such an association can create some difficulties for the cell when a part of the reticulum is damaged or when mitochondria should migrate from one cell region to another.
