How old are your organs?To scientists' surprise, organs are a mix of young and old cells
Vice President, Chief Science Officer and Professor Martin Hetzer, first author Rafael Arrojo e Drigo and colleagues discovered that the mouse brain, liver and pancreas contain populations of cells and proteins with extremely long life spans—some as old as the organism itself. The team’s methods could be applied to nearly any tissue in the body to provide valuable information about the lifelong function of nondividing cells and how cells lose control over the quality of proteins and cell structures during aging.
