What morphogen is necessary to specify neural crest cells after dorsal neural tube closure? Shh Wnt RA BMP TGF-beta Question 14 1 pts Hirschsprung disease (aka congenital aganglionic megacolon) stems from a failure of enteric nervous system (ENS) innervation of the distal colon resulting in the inability to pass stool. Scientists studying this disease are interested in modeling the ENS in culture beginning with human IPSCs. What cell type would the scientist need to first differentiate the iPSCsunto prior to generating ENS cells? (iPSCs to to enteric neurons) mesodermal cells somitic cells melanocytes neural crest celils
