Neural crest development
“Hot off the press” review of the neural crest development in the zebrafish model by CBC Catalyst Awardee Vicky Prince of UChicago
The neural crest is morphologically defined as two elongated strips of cells of ectodermal origin located along the margins of the neural tube of a vertebrate embryo. As the embryo develops, the neural crest cells (NCCs) migrate to many different locations and differentiate into many cell types eventually contributing to the different systems and organs (e.g., neural, skin, teeth, head, face, heart, adrenal glands, gastrointestinal tract) of the maturing organism.
Zebrafish is an excellent model system to study cell migration as the embryos are transparent, allowing for high-resolution real-time imaging. In addition, the system is enabled with powerful genetic and transgenic tools.
Victoria Prince, PhD, Professor at the Department of Organismal Biology and Anatomy, and Dean and Director of the Office of Graduate Affairs at UChicago, has recently published a comprehensive review of the neural crest development in the zebrafish model. The review, titled “Neural crest development: Insights from the zebrafish,” can be found in the Oct. 8 issue of Developmental Dynamics.
Prince is a CBC Catalyst Award recipient, which she received with Ankur Saxena of UIC in 2016, for the project “In Vivo Multicellular Dynamics of Neural Crest Stem Cell Migration.” The CBC funds are acknowledged as having partially supported Prince’s work that is included in the review. Congratulations!

Our understanding of the neural crest, a key vertebrate innovation, is built upon studies of multiple model organisms. Early research on neural crest cells (NCCs) was dominated by analyses of accessible amphibian and avian embryos, with mouse genetics providing complementary insights in more recent years. The zebrafish model is a relative newcomer to the field, yet it offers unparalleled advantages for the study of NCCs. Specifically, zebrafish provide powerful genetic and transgenic tools, coupled with rapidly developing transparent embryos that are ideal for high-resolution real-time imaging of the dynamic process of neural crest development. While the broad principles of neural crest development are largely conserved across vertebrate species, there are critical differences in anatomy, morphogenesis, and genetics that must be considered before information from one model is extrapolated to another. Here, our goal is to provide the reader with a helpful primer specific to neural crest development in the zebrafish model. We focus largely on the earliest events-specification, delamination, and migration-discussing what is known about zebrafish NCC development and how it differs from NCC development in non-teleost species, as well as highlighting current gaps in knowledge.
We are grateful to our colleagues in the neural crest field for helpful conversations that have influenced this article, and we apologize to the many individuals whose excellent work we were unable to cite due to space limitations. In particular, we thank Jon Clarke for his input to the section on neurulation, and Mary Halloran, Ankur Saxena, and Robert Ho and members of his group, for many helpful discussions. We also thank the expert reviewers of the initial version of the manuscript, whose insightful comments helped us to make significant improvements.
