Representative examples of IHC signals for Ob-R, ER, and PR in the six histological types of endometrial tissues studied here. For illustrative purposes, the tissues were ordered according to their relative expression score (high to low score for Ob-R)

Ob-R – leptin receptor, ER – estrogen receptor, PR – progesterone receptor, PE – proliferative endometrium, NAH – nonatypical hyperplasia, AH – atypical hyperplasia, EEC – endometrioid carcinoma, SE – secretory endometrium, NEC – nonendometrioid endometrial carcinoma.
