RESEARCH

In vertebrates, the central nervous system neurons arise from an extremely ordered tissue, the neuroepithelium. Our group is interested in understanding the mechanisms that underlie neuroepithelial differentiation (during neurulation) and neuronal differentiation, focusing in the roles and transitions of cell polarity during these processes. For this, we use both zebrafish and chick embryos. The zebrafish has great advantages for these studies, such as the accessibility to genetic manipulation and the unique optical transparency of embryos.
