Figure 4.

The effects of Bmp or Tgfβ activation on the cortical neurogenesis and OPC proliferation. A, Using the electroporated cortices from Figure 3, we stained Ctip2 to see the neurogenesis that occurs at the time of the electroporation and double stained Pdgfrα and Ki67 to see the OPCs in the active cell cycle. B, C, Plots were made from data collected from A to show the effects of the electroporated gene products on neurogenesis (B) and the proliferation of OPCs (C; n = 3). D, A plot was made from counting Blbp+ cells from the sections used in Figure 3 (n = 3). Scale bars: 100 μm. Error bars depict SEM.
