Fasting Gives Boost to Stem Cells

WASHINGTON (Dispatches)-Age-related declines in stem cell function can be reversed by a 24-hour fast, according to a new study.
According to a new study by researchers from Massachusetts Institute of Technology (MIT) biologists, it was found that fasting dramatically improves stem cells' ability to regenerate, in both aged and young mice.
In fasting mice, cells begin breaking down fatty acids instead of glucose, a change that stimulates the stem cells to become more regenerative. The researchers found that they could also boost regeneration with a molecule that activates the same metabolic switch. Such an intervention could potentially help older people recovering from GI infections or cancer patients undergoing chemotherapy, the researchers say.
"Fasting has many effects in the intestine, which include boosting regeneration as well as potential uses in any type of ailment that impinges on the intestine, such as infections or cancers," says Omer Yilmaz, an MIT assistant professor of biology, a member of the Koch Institute for Integrative Cancer Research, and one of the senior authors of the study. "Understanding how fasting improves overall health, including the role of adult stem cells in intestinal regeneration, in repair, and in aging, is a fundamental interest of my laboratory."
