Additional file 7 of Single-cell analysis of menstrual endometrial tissues defines phenotypes associated with endometriosis

Additional file 7. Stromal cell subclusters in ME samples map to stromal cell clusters found in first trimester decidua. We have compared the mapping of stromal subclusters reported by Vento-Tormo [26], based on the analysis of decidua in the first trimester, with the mapping of stromal cell subclusters we have described in menstrual effluent (ME). Note that our IGFBP1+ subcluster maps almost identically to the decidualizing stromal cell subset dS2 defined by Vento-Tormo [26]. In addition, our MGP+ subset shows a substantial overlap with dP2 and dP1 of Vento Tormo [26], subsets which are attributed to the perivascular stromal cells in first trimester decidua.
