Coexpression of Sox2 and Pax6 in mitotic cells.
Numbers represent the coexpression of Sox2 and Pax6 by mitotic cells in the developing rat somatosensory cortex. Cells were identified by Sox2 and/or Pax6 immunoreactivity in a minimum of three 200 µm radial unit sections at each age. Mitoses were identified by condensed chromatin in DAPI stained tissue. Numbers in parentheses indicate the total number of mitotic cells of each type (Sox2 or Pax6) that coexpress both proteins.
