Introduction
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.
Historically identified as "neural crest" by Arthur Marshall in 1879.[1] (see history below and original article).

Objectives
- Understand the structures derived from ectoderm.
- Understand the formation of neural folds.
- Identify the initial location of neural crest cells in the trilaminar embryo.
- Identify pathways of neural crest migration throughout the embryo.
- To know the major tissues to which neural crest cells contribute.
- To know how abnormalities in development that result from abnormal neural crest cell migration.
- Understand how neural crest cells contribute to the pharyngeal arches and the head structures they form.
Neural Crest Derivatives
A key feature of neural crest is the migration into other embryonic tissues to form specific neural and non-neural populations and structures.
Cranial neural crest
- migration - dorsolaterally and into pharyngeal arches
- craniofacial mesenchyme - cartilage, bone, cranial neurons, glia, and connective tissues of the face
- pharyngeal arches and pouches - thymic cells, tooth odontoblasts, middle ear bones (ossicles) and jaw (mandible)
Cardiac neural crest
- migration - located between the cranial and trunk neural crests, overlapping the anterior portion of the vagal neural crest.
- pharyngeal arches - (3,4,6) melanocytes, neurons, cartilage, and connective tissue
- heart outflow tract - aortic arch/pulmonary artery septum, large arteries wall musculoconnective tissue
Trunk neural crest
- migration - two major pathways over somites (dorsolaterally) and between somite and neural tube (ventrolaterally)
- dorsolateral - skin melanocytes
- ventrolaterally - dorsal root ganglia, sympathetic ganglia, adrenal medulla, aortic nerve clusters
Vagal and sacral neural crest
- migration - ventrally into surrounding splanchnic mesenchyme of gastrointestinal tract
- splanchnic mesenchyme - parasympathetic (enteric) ganglia of the gut
Development Overview
The following cranial and trunk data is based upon 185 serially sectioned staged (Carnegie) human embryos.[11]
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
Vagal Neural Crest
Recent research suggests that the vagal neural crest cells are a transitional population that has evolved between the head and the trunk, taking separate pathways to the both the heart and to the gut.[12][13]
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
Neck and Shoulder
A mouse study using individually labelled cells of postotic neural crest followed the development of the shoulder girdle (clavicle and scapula) that connects the upper limb to the axial skeleton.[14]
- Clavicle is a neural crest-mesodermal structure, posterior dermal clavicle mesoderm.
- Cryptic cell boundaries traverse apparently homogeneous skeleton of the neck and shoulders.
- Bones and muscles code of connectivity that mesenchymal stem cells of both neural crest and mesodermal origin obey
- Neural crest anchors the head onto the anterior lining of the shoulder girdle
- Hox-gene-controlled mesoderm links trunk muscles to the posterior neck and shoulder skeleton.
- Skeleton identified as neural crest-derived is affected in human Klippel-Feil syndrome, Sprengel's deformity and Arnold-Chiari I/II malformation.

Historic
The paper by Marshall, Morphology of the Vertebrate Olfactory Organ (1879)[1], was historically the first time the term "neural crest" was used. In his own earlier papers he had referred to this as a "neural ridge" in describing development of the chicken embryo neural tube.
See paper text and his referenced comment:
- "I take this opportunity to make a slight alteration in the nomenclature adopted in my former paper. I have there suggested the term neural ridge for the longitudinal ridge of cells which grows out from the reentering angle between the external epiblast and the neural canal, and from which the nerves, whether cranial or spinal, arise. Since this ridge appears before closure of the neural canal is effected, there are manifestly two neural ridges, one on either side ; but I have also applied the same term, neural ridge, to the single outgrowth formed by the fusion of the neural ridges of the two sides after complete closure of the neural canal is effected, and after the external epiblast has become completely separated from the neural canal. I propose in future to speak of this single median outgrowth as the neural crest, limiting the term neural ridge to the former acceptation. Thus, while there are two neural ridges, there is only one neural crest, a distinction that will be at once evident on reference to my former figures."
