Coexpression of Pax6 and Tbr2 in mitotic cells.

<p>Numbers represent the coexpression of Pax6 and Tbr2 by mitotic cells in the developing somatosensory cortex in each species. Cells were identified by Pax6 and/or Tbr2 immunoreactivity in a minimum of three 200 µm radial unit sections from each age in each species. Mitoses were identified by condensed chromatin in DAPI stained tissue. Numbers in parentheses indicate the total number of mitotic cells of each type (Pax6 or Tbr2) that coexpress both proteins.
