Abstract

During very early development in the embryo, cells migrate from the future brain. These cells, called neural crest cells, make there way to the nearest part of the gut, in the future oesophagus. They then migrate as a growing population right along the gut until they have populated the entire gut down to the rectum. To complicate matters, the gut itself is rapidly growing length-wise as this migration occurs. These neural crest cells then form the nerve cells that reside in the gut and which control gut function. In a common birth defect, Hirschsprung's disease, this migration stops short of the rectum so that the last part of the gut never develops nerve cells. This region lacking nerve cel..
