Mitochondria control stem cell fate

If the powerhouse of the cell, mitochondria, is disrupted, stem cells in the gut suffer, researchers have discovered. The human intestinal system covers an area of approximately 300 to 500 square meters due to its many protrusions (villi). This inner intestinal wall full of tiny bumps renews itself completely once every four to five days, a process which is guided by stem cells. Mitochondria are the powerhouse of a cell and provide energy through respiration, and play a crucial part in this process.
