Atoh1 KD analysis. (G, H) Atoh1 shRNA was introduced to P5 mice EGL together with H2B-EGFP plasmid and immunostaining for NEUROD1 (Cyan) and KI67 (magenta) was performed 24 hrs later. Nuclei of electroporated cells were labeled with GFP (green). Images of Control (G) and Atoh1 KD (H). Arrows indicate the cells of interest where GFP signals are co-localized with NEUROD1 and KI67.
