Lineage tracing of ectopic endometrium with (Gt)R26mTmG allele. (A–K) Bright-field images of mouse intestines and gynecologic tract following salpingectomy. (A′–K′) Fluorescent images of the same tissues, depicting cells derived from LtfCre^0/+;(Gt)R26^mTmG (n = 3) or LtfCre^0/+; (Gt)R26Pik3ca^*H1047R/^mTmG; Arid1a^fl/fl (n = 4) mice. In control mice, GFP expression was confined to the uterus (A–B). In LtfCre^0/+; (Gt)R26Pik3ca^*H1047R/^mTmG; Arid1a^fl/fl mice, lesions were observed on the omentum (C–E), the ovary (F–G) and the peritoneum (H–K). Ab: abdominal wall; Om: omentum; Ov: ovary; Ut: uterus.
