We all know that mitochondria are the powerhouse of cells because they generate energy from food. However, we did not know their involvement in cellular regeneration. Scientists at UT Southwestern Medical Center determined that liver cells with damaged mitochondria have less ability to regenerate when injured. Henceforth, allowing cells with undamaged mitochondria to grow more, rejuvenating the liver. This study was published in Science journal’s June 2024 issue.
