Introduction

Neural crest cell migration in the head region (chicken)

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

  • Cranial neural crest migration: new rules for an old road.[1] "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."
  • Derivation of neural crest cells from human pluripotent stem cells.[2] "Here we provide protocols for the step-wise differentiation of human embryonic stem cells (hESCs) or human induced pluripotent stem cells (hiPSCs) into neuroectodermal and NC cells using either the MS5 coculture system or a novel defined culture method based on pharmacological inhibition of bone morphogenetic protein and transforming growth factor-beta signaling pathways."
