PHLDA2 immunohistochemistry in the tammar yolk sac placenta. Both bilaminar and trilaminar yolk sac membranes are shown as the cord like structure in the sections (A: bilaminar yolk sac, B: trilaminar yolk sac). "T" indicates trophoblast cells, the large cells with large nuclei, and "En" indicates yolk sac endodermal cells, the flat and thin cells with relatively small nuclei.
