Our current understanding of how this diversity is generated is far from complete. Using Drop-seq to profile the single-cell transcriptomes of over 36,000 ventral telencephalic cells isolated from three distinct germinal zones (the ganglionic eminences), we found that regardless of their origin and ultimate fate, all lineages transit through one of three cardinal transcriptional programs that define the earliest branch points in cell fate determination. Thus, the ability of these germinal zones to generate distinct cells likely relies on the small number of genes that are differentially expressed within each of these regions. ER -
