EphA2 immunostaining (brown) on the Fallopian tube epithelium during normal menstrual cycle. a EphA2 was expressed on the apical membrane (triangle) and in the cytoplasm (arrow) of the tubal epithelial cells, including the ciliated cells and the secretory cells, while the staining intensities in the cytoplasm were weaker than those on the apical membranes. There was no staining evident in the interstitial cells. b EphA2 was present in the cilia of the ciliated cells (arrow). c Stronger stains were shown on the apical membranes of the tubal epithelial cells. d Negative control
