Neural Crest - Enteric Nervous System: Difference between revisions

Revision as of 07:05, 23 March 2013

Introduction

Human embryo neural crest cells (stage 11)

The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube. These cells migrate to many different locations and differentiate into many cell types within the embryo. This means that many different systems (neural, skin, teeth, head, face, heart, adrenal glands, gastrointestinal tract) will also have a contribution fron the neural crest cells.

In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) of the enteric nervous system.

These projects are the sole work of undergraduate science students and may contain errors in fact or descriptions.

Chicken embryo sequence shows the migration of DiI-labeled neural crest cells towards the branchial arches as the embryo. White rings indicate migration of individual cells. Each image represents 10 confocal sections separated by 10 microns.

 == Development Overview ==
-The following cranial and trunk data is based upon 185 serially sectioned staged (Carnegie) human embryos.<ref><pubmed>17848161</pubmed>| [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2375817 PMC2375817] | [http://onlinelibrary.wiley.com/doi/10.1111/j.1469-7580.2007.00773.x/full J Anat.]</ref>
-===Cranial Neural Crest===
-* '''stage 9''' - an indication of mesencephalic neural crest
-* '''stage 10''' - trigeminal, facial, and postotic components
-* '''stage 11''' -  crest-free zones are soon observable in rhombomere 1, 3, and 5
-* '''stage 12''' - rhombomeres 6 and 7 neural crest migrate to pharyngeal arch 3 and then rostrad to the truncus arteriosus
-* '''stage 13''' -  nasal crest and the terminalis-vomeronasal complex are last of the cranial crest to appear
-stages 9-14 - otic vesicle primordium descends
-===Trunk Neural Crest===
-Spinal ganglia increase in number over time and are in phase with the somites, though not their centre. There are 3 migratory pathways: ventrolateral between dermatomyotome and sclerotome, ventromedial between neural tube and sclerotomes, and lateral between surface ectoderm and dermatomyotome.
-* '''stage 13''' - about 19 present
-* '''stage 14''' - about 33 present
-* '''stage 15-23'''  - 30–35 ganglia
