Heat map of the hierarchical clustering of DEGs. (a) Clustering heat map of Wnt signal pathway correlated genes. (b) Clustering heat map of TGF-β/BMP signaling pathway genes. Each row represents the DEGs, and each column represents samples at a time point. Heat map uses FPKM value and then standardizes. Blue and red gradients indicate a decrease and increase in transcript abundance, respectively. The line on the left represents gene cluster, and the line on the top represents sample cluster.
