Clustering analysis of the miRNA counts in eutopic and ectopic tissue samples.

The edgeR plotMDS function was used to produce multi-dimensional scaling (MDS) plot in which distances reflect biological coefficient of variation between the studied samples. Dimension 1 represents different tissue types (endometria, healthy tissues, endometriotic lesions) while dimension 2 denotes different patients. Blue and green colours indicate different patients. Red circles represent endometriotic lesions, yellow circles adjacent healthy tissues and triangles with patient-specific colour denote respective endometria. The tissue samples presented in figure are following: patient E101 (blue)- endometrium E1011, lesions E1012, E1014, matched healthy tissue E1013; patient E47 (green) - endometrium E471, lesions E473, E475, E478, matched healthy tissues E474, E476, E479.
