a Heatmap visualizations of selected neuronal markers. b, c Organoid sections immunostained for TBR1, and SATB2 (b) and CTIP2, and CUX1 (c) and relative distributions of cells expressing these markers the marked ROIs. d Percentages of cells expressing cell different neuron type-specific markers (n = 8 [CTIP2], 5 [TBR1], 6 [SATB2], 5 [CUX1] and 5 [GABA/GAD67] organoids/1–2 sections per organoid produced in 2–3 batches from 2242-5 and EP2-15 lines). e Organoid sections immunostained for Calretinin (CALR) and GAD67; Calbindin (CALB) and GABA; Somatostatin (SST) and GABA; Parvalbumin (PV) and GABA; and Vasoactive intestinal peptide (VIP) and GAD67. f Percentages of inhibitory neurons expressing different interneuron markers (n = 4 organoids/1–3 sections per organoid, produced in four batches from 2242-5, EP2-15, H9, and EYQ2-20 lines). Data are presented as mean ± s.e.m. Scale bars = 200 and 20 (zoom-in) (b, c) and 50 (e) μm. Source data are provided as a Source Data file.
