Loss of kif11 causes an accumulation of radial glia in mitosis. (A–H) Lateral views of kif11-/- sibling neural tubes fixed at timepoints throughout neurogenesis and labeled for radial glia (Gfap), Phosphohistone H3 (PH3) and acetylated Tubulin (AT). Within all siblings, most Gfap+ cells labeled with our antibody were PH3+, indicating these cells were actively proliferating at the time of fixation (A,E insets). At all time points assayed, there were significantly more Gfap+/PH3+ cells in kif11-/- embryos compared with wild type siblings (E–H, quantified in I, asterisks), as well as more PH3+ nuclei (J, shaded and black bars). No change in the number of Gfap+ cells was seen between 20–25 hpf and 36–48 hpf within kif11-/- (I, brackets). Of all proliferating cells (J), it was noted that an unidentified population (PH3+, Gfap) is also kif11 dependent in both wild type and kif11-/- neural tubes. Error bars delineate the standard error of the mean. Asterisks indicate a statistical significance (t-test, two tailed, assuming equal variances, p<0.05). |
