In this sample taken from a mouse small intestine, a network of neural precursor cells is highlighted in green. Johns Hopkins researchers have discovered that these stem-like precursors constantly generate nerve cells. The gut’s blood vessels are highlighted in blue and the cell nuclei are gray. Every day, the researchers say, the gut loses and regenerates about five percent of its nerve cells. Over the course of a few weeks, the whole enteric nerve system turns over.
