Neural crest multipotency and specification: power and limits of single cell transcriptomic approaches

Area of Science:

• Developmental Biology
• Cell Biology
• Genomics

Background:

• Neural crest cells are multipotent cells in vertebrate embryos.
• They generate diverse cell types like neurons, glia, bone, and melanocytes.
• Neural crest formation involves specific signaling pathways and sequential cell states.

Purpose of the Study:

• To review recent advances in understanding early neural crest formation.
• To discuss how high-throughput single-cell sequencing has improved knowledge of neural crest lineage commitment and specification.
• To highlight remaining questions in neural crest biology.

Main Methods:

• Review of scientific literature from 2017-2021.
• Analysis of high-throughput single-cell sequencing data.
• Discussion of transcriptomic data in neural crest development.

Main Results:

• Single-cell sequencing has advanced understanding of neural crest cell lineage commitment and specification.
• New insights into mechanisms driving multipotency and diversification have been gained.
• Transcriptomic data reveals sequential cell states during neural crest development.

Conclusions:

• High-throughput single-cell sequencing is a powerful tool for studying neural crest development.
• Further research using these approaches is needed to resolve remaining questions.
• Understanding neural crest biology has implications for developmental biology and regenerative medicine.
