Hematoxylin and eosin (H&E) staining (A,B) and immunohistochemical analysis of the expression of IGF1R (C,D) and IGF2R (E,F) of the endometrium in post-natal dairy cows. In A, large amounts of eosin-stained (orange arrows) secretions are found in glandular, and blood vessel congestion and thrombosis (green) are widespread, as are the massive neutrophils (yellow) in both luminal epithelium and stroma sections. B shows that the shape of cytoplasm and nucleus is uniform in the endometrium. The positive-immunostained immune cells are shown by the arrows in C, D, E and F. Scale bars = 100 μm.
