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) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs.

In the head region, neural crest cells migrate into the pharyngeal arches (as shown in movie below) forming ectomesenchyme contributing tissues which in the body region are typically derived from mesoderm (cartilage, bone, and connective tissue).General neural development is also covered in Neural Notes.

Some Recent Findings

  • The role of the transcription factor Rbpj in the development of dorsal root ganglia[1] "The dorsal root ganglion (DRG) is composed of well-characterized populations of sensory neurons and glia derived from a common pool of neural crest stem cells (NCCs), and is a good system to study the mechanisms of neurogenesis and gliogenesis. Notch signaling is known to play important roles in DRG development, but the full scope of Notch functions in mammalian DRG development remains poorly understood."
  • Cranial neural crest migration: new rules for an old road.[2] "In this review, we discuss recent cellular and molecular discoveries of the CNCC migratory pattern. We focus on events from the time when CNCCs encounter the tissue adjacent to the neural tube and their travel through different microenvironments and into the branchial arches. We describe the patterning of discrete cell migratory streams that emerge from the hindbrain, rhombomere (r) segments r1-r7, and the signals that coordinate directed migration."

Development Overview

The following cranial and trunk data is based upon 185 serially sectioned staged (Carnegie) human embryos.[4]

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
