Old gut stem cells made to grow like young ones in a dish

Intestines experience a lot of wear and tear. Without the stalwart stem cells that live in our gut’s lining, our ability to absorb food would dwindle and bacteria from the digestive tract would be able to breach the bloodstream. Unfortunately, the regenerative abilities of intestinal stem cells decline with age. However, it may be possible to partially reverse aging in gut stem cells, at least in a petri dish.
