Regarding tissue type preference, the C0 FHL2+ Fibroblast and C2 CXCR4+ Fibroblast subpopulations were more common in Endometriomas, while the C3 RAMP1+ Fibroblast, C1 SFRP2+ Fibroblast, and C4 TFF3+ Fibroblast subpopulations were predominantly found in Endometriosis. This evidence concerns the gene RAMP1 and endometriosis.
