CBF:H2B-Venus expression during brain development. Epifluorescent widefield images of E13.5 (A, A1), E16.5 (B, B1), P0 (C, C1) and P21 (D, D1) depicting CBF:H2B-Venus expression in the dorsal (A, B, C, and D) and ventral (A1, B1, C1 and D1) part of the brain. Laser confocal images of sections through the brain of stages E13.5 (E, F), E16.5 (G, G1), P0 (H, H1, H2, H3) and P21 (I, I1, J and J1) expressing CBF:H2B-Venus stained with Hoechst and Phalloidin to label nuclei and F-Actin, respectively.
