SEM imaging of maternal decidual epithelium. The decidual tissue is from normal pregnant mice of NP group and aborted mice of A30Z group. The diameter of the tissue, which was fixed in 2.5% glutaraldehyde before preparing ultra-thin section, is 1 mm. After uranium and lead staining, the sections were analyzed by Teneo SEM scanning electron microscope (FEI, U.S.A). Arrowheads indicate microvilli. Arrows indicate pinopodes. Representative images of three samples for each group are shown. The scale bars on the two columns on the left are 1μm, and the scale bars  on the one column on the right are 500 nm
