Fig. 1From: A comparative analysis of the intrauterine transcriptome in fertile and subfertile mares using cytobrush samplingHeat map and hierarchical cluster analysis of DEGs between subfertile and fertile mares (FDR < 0.1). Each row represents 1 DEG, each column 1 sample. Red color represents higher and blue color lower expression of the gene compared to the mean of all samples (mean-centered values in log2 scale from −3 to 3)Back to article page
