Diagrammatic representation of experimental endometriosis induction in mice and histological representation of ectopic endometriotic implant.

A) Diagram depicts donor mice (and genotype) from which endometrial tissue was dissected and separated into myometrium and endometrium (stromal and epithelial components), transfer of 10 equal size (1 mm3) endometrial fragments to recipient mice and subsequent assessment of establishment of ectopic “endometriotic implants.” B) histological representation of “endometriotic implant” with red boxed area enlarged in C) white arrow indicates epithelial component and stromal compartment and underlying peritoneum are labeled. Notice the stromal and peritoneal contact at the site of implant attachment. White scale bar = 50 um.
