Representative LYVE-1, CD31, and cytokeritin expression in placental villous tissue. (A) villous stained with anti-LYVE-1; (B) villous stained with anti-CD31; and (C) villous stained with anti-cytokeritin 7. Arrowheads indicate villous fetal vessel endothelial layer (EC) and arrows indicate syncytiotrophoblast layer (TCs). A and B, not C, were counterstained with hematoxylin/eosin.
