Figure Lengend Snippet: a , Control, patient, knock-in, and rescue organoids at D50 immunostained for apoptotic cell marker cleaved-caspase 3 (CC3). Dashed yellow lines delineate the SVZ/VZ. b , Quantification of CC3 + cells per mm 2 SVZ/VZ area. c , Control, patient, knock-in, and rescue organoids at D50 immunostained for oRG cell marker HOPX. Dashed yellow lines delineate the SVZ/VZ. d , Quantification of HOPX + cells per mm 2 SVZ/VZ area. e , Control, patient, knock-in, and rescue organoids at D70 immunostained for IPC marker TBR2. Dashed yellow lines delineate the SVZ. f , Quantification of TBR2 + cells per mm 2 SVZ area. g , Control, patient, knock-in, and rescue organoids at D70 immunostained for oRG marker HOPX, TBR2, and CC3. h , i , Quantification of the faction of CC3 + cells co-expressing either TBR2 ( h ) or HOPX ( i ). n = 12 cortical regions, n = 6 organoids, 2 batches of 3 organoids per genotype ( b, d, f ); n = 6 cortical regions, n = 6 organoids, 2 batches per genotype ( h, I ). Statistical test: one-way ANOVA; ****, P < 0.0001; **, P < 0.01; *, P < 0.05; ns, not significant. Scale bars, 100 µm ( a, c, e ) and 50 µm ( g ).
