A) Number of differentially expressed genes (DEGs), including up-regulated (UP) and down-regulated (DOWN) gens in P1 cells compared to P0 cells. B) Correlation analysis between P0 and P1 samples. C) Volcano plot of gene expression profile in P1 cells versus P0 cells; up, nosig, and down indicates up-regulated genes, non-significantly differentially expressed genes, and down-regulated genes, respectively. D) Heatmap of DEGs in P0 and P1 cells.
