C-F. Ccnd1 KD analysis. (C, D) Ccnd1 shRNAs together with H2B-EGFP plasmid were introduced to P5 mice EGL and immunostaining for ATOH1 (magenta) and KI67 (Cyan) was performed the following day. Nuclei of electroporated cells were labeled with GFP (yellow). Images of Control (C) and Ccnd1 KD (D). Arrows indicate the cells of interest where GFP signals are co-localized with ATOH1. (E) Proportions of ATOH1+, KI67+ cells (AT+GCPs) among the electroporated cells were decreased in the Ccnd1 KD mice. (F) Proportions of KI67+ cells (total GCPs) were not significantly changed. Student T-test was performed between Control (N=3) and Ccnd1 KD (sh#1: N=3, sh#2: N=3) mice. Bars and error bars are representing as Mean ± SEM. ***p < 0.001, N.S.: Not Significant. Number of cells: 52, 64 and 107 cells from N=3 mice (scramble), 72,79 and 75 cells from N=3 mice (sh#1), 84, 70 and 40 cells from N=3 mice (sh#2).
