Figure 1. Immunohistochemical staining for macrophage markers in term placental tissue.

Figure 1

Immunohistochemical staining for M1 macrophage markers, CD11b (ITGAM) (A) and CD40 (B) and M2 macrophage markers CD163 (C) and FR-β (D), was carried out using formalin-fixed paraffin embedded sections. Staining with negative control antibody is shown in the Panel A insert. Results are presented from one placenta representing three different placentas. Arrows indicate stained HBCs, arrowheads denote the syncytiotrophoblast, and the asterisk denotes a fetal capillary. Bar; 20 μm.
