New research at Washington University School of Medicine in St. Louis indicates stem cells located in “pockets” in the intestine avoid contact with a prominent metabolite produced by beneficial microbes living in the gut. That metabolite – butyrate – restricts the proliferation of stem cells, potentially hampering the intestine from repairing itself after an injury or damage.

Similarly, the rates of marijuana use by young people are falling despite the fact more U.S. states are legalizing or decriminalizing marijuana use and the number of adults using the drug has increased. Researchers at the School of Medicine examine the data.
