Role of L1CAM in enteric nervous system development

There are millions of nerve cells in the gut. During development, these nerve cells arise from cells (neural crest) that migrate from the developing brain. Neural crest cells migrate into and along the gut. Some humans have a condition called Hirschsprung's disease in which nerve cells are absent from parts of the gut. Afflicted individuals have severe constipation and require surgery. In this study, we will identify the mechanisms controlling neural crest migration in the developing gut.
