To further explore the effect of miR‐488 on the Wnt signalling pathway by regulating FZD7, the endometrial glandular epithelial cells were extracted from the endometrial glandular epithelial tissues from normal and endometriosis mice and then identified, and the results (Supporting Information Figure S1) showed that cells under a microscope presented obvious epithelioid cell morphology and the positive cells of cytokeratin staining accounted for 80%. Here, FZD7 is linked to endometriosis.
