| Research Abstract |
Here we aimed to identify the genes that are involved in the temporal and spatial regulation of neocortical progenitors by comparing the gene expression profiles of the cells at four different developmental stages of mouse embryos(E10.5, E12.5, E15.5, and E18.5). We found that DmrtA family genes, encoding putative transcription factors, were predominantly expressed in early stages of neuroepithelial cells. We also found that Dmrt3 and Dmrta2 mutants exhibited the abnormal development of the telencephalon. These data thus suggest that Dmrt family genes are involved in the regulation of the spatiotemporal diversity of the process of neuroepithelial cell differentiation.
