Heat maps of GO enrichment analysis for epithelial cell proliferation and differentiation-related DEGs. a Up-regulated DEGs. b Down-regulated DEGs. Up or down-regulated DEGs at each time point were submitted to GO enrichment analysis using GOEAST web-based software ( The results of GO enrichment analysis are displayed in Additional file 2: Table S2. Biological function in GO terms involved in epithelial cell proliferation and differentiation were selected to display in heat maps according to the statistical significance (P < 0.05). Columns and rows in the heat maps indicate treatments and enriched biological process GO terms, respectively. Sample names are displayed above the heat maps. Color scales indicate P values of enrichment tests and gray cells represent an empty value or a value > 0.05
