Migration of neural crest-derived enteric nervous system precursor cells to and within the gastrointestinal tract.
The enteric nervous system, the intrinsic innervation of the gastrointestinal tract, consists of large numbers of phenotypically diverse neurons and glial cells, arranged in complex interconnecting plexuses situated between the smooth muscle layers of the gut wall. Recently, the enteric nervous system has attracted much attention from developmental biologists whose efforts have focused on analy...
متن کاملMeis3 is required for neural crest invasion of the gut during zebrafish enteric nervous system development
During development, vagal neural crest cells fated to contribute to the enteric nervous system migrate ventrally away from the neural tube toward and along the primitive gut. The molecular mechanisms that regulate their early migration en route to and entry into the gut remain elusive. Here we show that the transcription factor meis3 is expressed along vagal neural crest pathways. Meis3 loss of...
متن کاملBMP signaling is necessary for neural crest cell migration and ganglion formation in the enteric nervous system
The enteric nervous system (ENS) is derived from neural crest cells that migrate along the gastrointestinal tract to form a network of neurons and glia that are essential for regulating intestinal motility. Despite the number of genes known to play essential roles in ENS development, the molecular etiology of congenital disorders affecting this process remains largely unknown. To determine the ...
متن کاملHow Tissue Mechanical Properties Affect Enteric Neural Crest Cell Migration
Neural crest cells (NCCs) are a population of multipotent cells that migrate extensively during vertebrate development. Alterations to neural crest ontogenesis cause several diseases, including cancers and congenital defects, such as Hirschprung disease, which results from incomplete colonization of the colon by enteric NCCs (ENCCs). We investigated the influence of the stiffness and structure ...
متن کاملNeural crest regionalisation for enteric nervous system formation: implications for Hirschsprung's disease and stem cell therapy.
Midbrain, hindbrain and vagal neural crest (NC) produced abundant enteric nervous system (ENS) in co-grafted aneural hindgut and midgut, using chick-quail chorio-allantoic membrane grafts, forming complete myenteric and submucosal plexuses. This ability dropped suddenly in cervical and thoracic NC levels, furnishing an incomplete ENS in one or both plexuses. Typically, one plexus was favoured o...
