Mihaylova et al show that short-term fasting promotes intestinal stem and progenitor cell function in young and aged mice by inducing a robust fatty acid oxidation (FAO) program; PPAR (peroxisome proliferator-activated receptor) agonists emulate these effects, showing that fatty acid metabolism has positive effects on young and old intestinal stem cells.
