Fig. 4. EtOH alters astrocytic and synaptic protein quantities and promotes differential protein abundance in cortical organoids.

a, b Western blot and quantification of astrocytic and synaptic protein markers in cortical organoids during development (two-way ANOVA for each protein; *P < 0.05, **P < 0.01, ***P < 0.001; n = 3 replicates (~5–10 organoids)/condition from independent organoid batches from the WT83 iPS cell line). c Principal components analysis of protein digital spatial profiling distinguishes distinct clusters between proliferative and non-proliferative regions and between EtOH-exposed and control samples (n~10 control and EtOH-exposed organoids) (d) Heatmap showing variation in protein abundance in organoid samples between distinct spatial and EtOH-exposure clusters. e Volcano plot of proliferative (rosette) regions from control and EtOH-exposed organoids highlights the differences in expression of various proteins. Green bar represents a P value of 0.05.
