Most mitotic Pax6+ cells express Sox2 during and after neurogenesis.

<p>(<b>a</b>) Coronal section from E17 rat somatosensory cortex immunostained for Pax6 (red) and Sox2 (green) and counterstained with DAPI (blue). Boxes (1 and 2) show examples of Pax6+ mitotic cells that also express Sox2. (<b>b</b>) Coronal section from P3 rat somatosensory cortex immunostained for Pax6 (red) and Sox2 (green) and counterstained with DAPI (blue). Boxes (1 and 2) show examples of Pax6+ mitotic cells that also express Sox2. There was greater overlap of Pax6 and Sox2 expression at E17 than at P3, but the extent of colabeling in mitotic cells was similar at each age (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030178#pone-0030178-t014" target="_blank">Table 14</a>). Scale bar in (<b>a</b>) applies to all images.
