The primary aim of our research group is to elucidate the mechanism that underlies the development of the Neural Crest.
We would like to know how Neural Crest cells acquire their identity within the ectoderm and how their migration and differentiation is controlled.
The Neural Crest is a group of cells found in all vertebrate embryos. It forms in the neural folds at the border of the neural plate and gives rise to the Peripheral Nervous System, as well as the cartilage, bone and muscle in the face and neck, pigmented cells in the skin, several endocrine glands and part of the heart. It is this extraordinary ability of the Neural Crest to become many different types of cell that has attracted the attention of many biologists. The second astonishing characteristic of neural crest cells is that they are able to migrate very long distances in the embryo. The neural crest has been called the “explorer of the embryo” as it is one of the embryonic cell types that migrate most during development, eventually colonizing almost every tissue.
The primary aim of our research group is to elucidate the mechanism that underlies the development of the Neural Crest. We would like to know how Neural Crest cells acquire their identity within the ectoderm and how their migration and differentiation is controlled. We study neural crest development in zebrafish and frog ( Xenopus laevis) embryos as these two animal models offer several complementary advantages.
