Dynamic progression of the common DEGs in the Meishan and Yorkshire endometrium. (A) Unsupervised hierarchical clustering of the 228 annotated common DEGs in the Meishan and Yorkshire endometrium. The common DEGs were clustered into four groups. Red region, genes up-regulated in the endometrium; green region, genes down-regulated in the endometrium.
