I thought stem cells aren't effective when taken orally? Turns out that's right, and the headline is misleading - these stem cells COME FROM the mouth, but are injected. The study offers a compelling new perspective on TBI: that its harmful effects go beyond the brain — affecting #Gut Health too. And importantly, administering oral mesenchymal stem cells may help dampen the inflammatory and oxidative aftermath in the digestive system, preserving tissue integrity. If this line of research holds up in humans, it could broaden how we treat brain injuries — from purely neurological care to an integrated, body-wide healing strategy. #Brain Journey Network bioengineer.org/oral-stem..
