  • migrate
  • The CNCCs, with the assistance of their filopodia and lamellipodia (actin containing extensions of cytoplasm that allow a cell to probe its path of migration), leave the neural tube and migrate along a dorsolateral pathway to the circumpharyngeal ridge. (wikipedia.org)
  • regulates
  • Here, we demonstrate a new function for PTK7 in Xenopus neural crest migration and use this system in combination with in vitro assays to define the intersection of PTK7 with the non-canonical Wnt signaling pathway that regulates PCP. (biologists.org)
  • Thus, PTK7 regulates neural crest migration by recruiting dsh, providing molecular evidence of how PTK7 intersects with the PCP signaling pathway to regulate vertebrate cell movements. (biologists.org)
  • somites
  • i) Detail of the migration of the ventro‐medial trunk neural crest cells in between epithelial somites, through the sclerotome and aggregating to form ganglia of the peripheral nervous system. (els.net)
  • E) Early expression of cre is seen to the anterior extent of NC (arrow) flanking the neural keel at 6 somites. (nih.gov)
  • tube
  • Neural tube defects occur before the eighth week of gestation when many women may not be aware of the pregnancy. (wisegeek.com)
  • Most women are advised to begin a daily supplement of folic acid and prenatal vitamins several months before trying to become pregnant to help prevent neural tube defects from occurring. (wisegeek.com)
  • The neural crest is a population of cells that emigrates from the dorsal neural tube during early embryogenesis and migrates extensively to give rise to a myriad of cell types. (els.net)
  • The cells localise near the dorsal aorta to form the sympathetic ganglia (SY), align along the ventral root motor fibres (VR) and differentiate into glial cells, or coalesce near the dorsal neural tube and constitute the sensory or dorsal root ganglia (DRG). (els.net)
  • This is followed by migration away from the neural tube. (els.net)
  • See also neural tube formation . (thefreedictionary.com)
  • Body (spinal cord level) - lateral edges of fused neural tube. (edu.au)
  • The secretion of Wnt inhibitors (such as Cerberus, Dickkopf and Crescent) by the anterior endoderm also prevents Wnt3a and Wnt8 secreted by the neural tube from inhibiting heart formation. (wikipedia.org)
  • Mutations in this gene may be associated with sporadic cases of neural tube defects. (wikipedia.org)
  • The neural-crest stem cells split from the neural tube as it closes, and nociceptors grow from the dorsal part of this neural-crest tissue. (wikipedia.org)
  • Conversely, the expression of the N-cadherins remains unchanged in the other regions of the neural tube that is located on the anterior-posterior axis of the vertebrate. (wikipedia.org)
  • The neural crest cells that are found outside of a given neuromere will express the same proteins as the cells that are found inside the neural tube. (wikipedia.org)
