Figure 1. Induction and neurogenic conversion of hESC-derived midbrain FP precursors is dependent on CHIR99021 addition.
a) Immunocytochemistry at day 11 for FOXA2 (red), NESTIN (green, upper panels), LMX1A (green, middle panels) and OTX2 (green, lower panels). b,c) Quantification of the data presented in (a); mean ± SEM, n=3 (independent experiments): *** p < 0.001; ** p < 0.01; p < 0.05 (compared to LSB, Dunnett test). d) Diagram of culture conditions. e,f) Selected lists of differentially expressed transcripts at day 11 comparing LSB/S/F8/CHIR versus LSB (e) or versus LSB/S/F8 (f). g,h) Temporal gene expression analysis for markers of midbrain DA precursor (g), forebrain and ventral non-DA precursor identity (h). Scale bars: 50 μm.
