Wnt signaling regulates the growth of gastric organoids in air-liquid interface. The growth of organoids were examined using stereoscope (a) and Ki67 staining (b) at Day 21 after treating with 10 uM LGK974 for 7 days. 0.1% DMSO in organoid growth media as the vehicle control. (c) Differentially expressed Wnt related genes between epithelial and fibroblast cells. Genes with fold change >1.5 (|Ln| > 0.4) and Bonferoni adjusted p < 0.05 were labeled in red with gene name. The x-axis is the natural log transformed fold change of gene expression in epithelial vs mesenchymal cells. The y-axis is the −log10 transformed p value.
