Fig. 2From: An immunohistochemical study on the expression of sex steroid receptors, Ki-67 and cytokeratins 7 and 20 in feline endometrial adenocarcinomasER-α and PR immunohistochemical expression in feline normal and neoplastic endometrium. a. ER-α and b. PR in the LS of cyclic endometrium are expressed in all uterine layers. BAR = 250 μm c. ER-α expression is decreased in FEA. Transition between positive normal glands and negative neoplastic cells are notorious. BAR =100 μm. d. PR expression is maintained in FEA. BAR =100 μm.
