now provide strong evidence for the role of the hydrogen sulfide (H2S) gas in the protective effects of calorie and protein restriction against ischemia/reperfusion injury (IRI) but also implicate H2S in longevity extension in model organisms.
Intrinsic epithelial cells repair the kidney after injury.
Boston, United States. In Cell Stem Cell, 2008
Two days after ischemia-reperfusion injury (IRI), 50.5% of outer medullary epithelial cells coexpress Ki67 and RFP, indicating that differentiated epithelial cells that survived injury undergo proliferative expansion.
