The influence of enteric neural crest cells on the trajectory of pathfinding enteric neurons and whether these leading neural crest cells expresses membrane receptors or diffusible proteins to instruct the growing neurons. Also determine the guiding element of neural crest cells toward the caudal end of the gut. Introduction: The enteric nervous system (ENS) is responsible for the regulation of key aspects of the gastrointestinal tract like motility, secretion and flow of the blood. ENS is derived principally from the neural crest cells (NCC) of vagal and sacral regions of neural tube and regulate the intestinal peristalsis. The normal ENS development during embryogenesis is essential for a healthy gut, as the defects in this process leads to Hischsprung disease (HSCR), the most common neurocristopathy in humans.
