Can Metabolic Mechanisms of Stem Cell Maintenance Explain Aging and the Immortal Germline?

Cell Stem Cell. 2015 Jun 4;16(6):582-4. doi: 10.1016/j.stem.2015.04.021.

Abstract

The mechanisms underlying the aging process are not understood. Even tissues endowed with somatic stem cells age while the germline appears immortal. I propose that this paradox may be explained by the pervasive use of glycolysis by somatic stem cells as opposed to the predominance of mitochondrial respiration in gametes.
