Overexpression of atoh7, otx2, and ptf1α in vsx1+ and OC1+ RPCs. (A) Representative images of vsx1+ cells (labeled by tdTomato-NLS) after overexpressing atoh7, otx2, and ptf1α in vsx1+ RPCs with no TF overexpression as the blank. Tg(ptf1α:GFP) was used to indicate cell body location. (B) Cell type distribution of vsx1+ cells in A. The significant increase of each neuron type compared with blank is shown. (C and D) Vsx1+ AC subtypes after ptf1α overexpression. Representative image of glyT1+ ACs is shown in C. Zoom-in images in the yellow rectangle are shown on the right side. Statistic distribution of vsx1+ AC subtypes is shown in D. (E) Representative images of OC1+ cells (labeled by tdTomato-NLS) after overexpressing atoh7, otx2, and ptf1α in OC1+ RPCs with no TF overexpression in the blank. (F) Cell type distribution of OC1+ cells in E. The significant increase of each neuron type compared with blank is shown. (G and H) OC1+ AC subtypes after ptf1α overexpression. The image of a gad1b+ AC is shown in G. Zoom-in images in the yellow rectangle are shown on the right side. Statistical distribution of OC1+ AC subtypes is shown in H. (I) A summary graph. Scale bar, 10 µm. **, P < 0.001; ***, P < 0.0001 (Fisher's exact test).
