Source: Fasting Gives a Boost to Stem Cells
A drug treatment that mimics fasting can also provide the same benefit, study finds
Summary:
Age-related declines in stem cell function can be reversed by a 24-hour fast, according to a new study. Biologists found fasting dramatically improves stem cells' ability to regenerate, in both aged and young mice.
Intestinal stem cells from mice that fasted for 24 hours, at right, produced much more substantial intestinal organoids than stem cells from mice that did not fast, at left.
As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections or other conditions that affect the intestine.
"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."

buttons. LOLing at this scientific news?
