The intestinal nervous system controls several functions of the gastrointestinal tract, and when impaired causes bowel abnormalities. Now, a group of American researchers has generated intestinal tissue from embryonic and iPS cells (this last hasn’t ethics problems), using them to study the molecular basis of Hirschsprung disease. In the authors’ opinion, this is the first time that functional intestinal tissue has been produced that can be used to study motility disorders of the human gastrointestinal tract (See HERE).
