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) 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

  • Neuronal differentiation in the developing human spinal ganglia[1] "The spatiotemporal developmental pattern of the neural crest cells differentiation towards the first appearance of the neuronal subtypes was investigated in developing human spinal ganglia between the 5th -10th developmental week using immunohistochemistry and immunofluorescence methods. First NF200 (neurofilament-200, likely-myelinated mechanoreceptors) and isolectin-B4 positive neurons (likely-unmyelinated nociceptors) appeared already in the 5/6th developmental week and their number subsequently increased during progression of development. Proportion of NF200 positive cells was higher in the ventral parts of the spinal ganglia than in the dorsal parts, particularly during the 5/6th and 9/10th developmental weeks (Mann-Whitney, p=0.040 and p=0.003). NF200 and IB4 co-localized during the whole investigated period. Calcitonin gene-related peptide (CGRP, nociceptive responses), vanilloid-receptor-1 (VR1, polymodal nociceptors) and calretinin (calcium signalling) cell immunoreactivity first appeared in the 6th and 8th week, respectively, especially in the dorsal parts of the spinal ganglia. VR1 and CGRP co-localized with NF00 during the whole investigated period. Our results indicate the high potential of early differentiated neuronal cells, which slightly decreased with progression of spinal ganglia differentiation. On the contrary, the number of neuronal subtypes displayed increasing differentiation at later developmental stage."
  • The role of the transcription factor Rbpj in the development of dorsal root ganglia[2] "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.[3] "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.[5]

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

(A and B) NCC migration pathways at 9.5 dpc.

  • A - In wild-types, only a few intermediate wave NCCs are NRP1-negative (green) and travel alongside intersomitic and perisomitic vessels (red). Rather, most NCCs are NRP1-positive (yellow) and are channeled into the anterior sclerotome by repulsive SEMA3A signals. Accordingly, Sema3A (blue) is expressed in 2 domains, a narrow stripe in the dermomyotome adjacent to the preceding intersomitic furrow, and a broader domain in the posterior dermomyotome that extends into the posterior sclerotome.
  • B - In the absence of NRP1 signaling, intermediate wave NCCs are blind to SEMA3A (now shown in gray) and preferentially migrate alongside intersomitic blood vessels (red), similar to early wave NCCs. (C and D) Peripheral neuron position in wild-types and Nrp1-null mutants at 11.5 dpc reflects the migratory patterns of their NCC precursors.
  • C - In wild-types, sensory neurons condense into segmentally arranged dorsal root ganglia in the anterior sclerotome of the somites, while sympathetic neurons form paired, but nonsegmented primary sympathetic cords next to the dorsal aorta.
  • D - In the absence of SEMA3A/NRP1 signaling, sensory and sympathetic neurons differentiate in ectopic positions corresponding to the earlier position of their NCC precursors. Consequently, both the segmentation of the sensory system and the assembly of the sympathetic cords are disrupted.
