Target type: biologicalprocess
The process in which a cell becomes committed to become a neural crest cell. [GOC:dh, GOC:ef]
Neural crest cells (NCCs) are a transient multipotent cell population that arises from the dorsal neural tube during vertebrate embryogenesis. NCCs are highly migratory and contribute to a diverse array of cell types and tissues, including neurons, glial cells, pigment cells, cartilage, bone, and smooth muscle. The fate commitment of NCCs is a complex process involving a precise interplay of intrinsic factors and extrinsic signals.
**Intrinsic factors** play a crucial role in establishing the basic developmental program of NCCs. Transcription factors, such as Snail, Slug, and Sox9, are expressed in NCCs and contribute to their specification and migration. These factors act by regulating the expression of genes that control cell fate, cell adhesion, and motility.
**Extrinsic signals** from the surrounding environment influence NCC fate commitment by providing positional cues and directing differentiation pathways. These signals include growth factors, such as fibroblast growth factors (FGFs), Wnt proteins, and bone morphogenetic proteins (BMPs).
**NCC fate commitment** is a multi-step process that involves several distinct stages.
1. **Specification:** During gastrulation, cells in the dorsal neural tube are specified to become NCCs through the expression of specific transcription factors and signaling molecules.
2. **Migration:** NCCs migrate from the neural tube to their target locations in the embryo, guided by chemoattractant and chemorepellent cues.
3. **Proliferation:** NCCs undergo extensive proliferation to increase their number and expand their potential for differentiation.
4. **Differentiation:** Once they reach their target locations, NCCs differentiate into various cell types, depending on the specific signals they receive from their environment.
**Differentiation into specific cell types is influenced by:**
* **Growth factors:** FGFs, BMPs, and Wnt proteins promote differentiation into specific cell lineages, such as neurons, glia, and melanocytes.
* **Transcription factors:** Pax6, Phox2b, and Mitf are examples of transcription factors that control the differentiation of NCCs into neurons, autonomic neurons, and melanocytes, respectively.
* **Cell-cell interactions:** Interactions between NCCs and their surrounding tissues can influence their fate commitment.
**The commitment of NCCs to specific fates is a highly regulated process** that ensures the proper development of various tissues and organs. Disruptions in this process can lead to developmental defects, such as neural tube defects, pigmentation disorders, and craniofacial abnormalities.'
