Proliferation of subplacenta trophoblast. (A,B) Early pregnancy, PCNA, negative IgG controls below. The subplacenta (sp), which is highly lobed and situated around the central excavation (ce), shows a high degree of proliferation activity, related to the layer of cellular trophoblast (ct). The syncytial trophoblast (syt) on the other side of the lobes faces towards the maternal blood channels (mbc). Some fetal capillaries (fc) are already present. Scale bars = 0.1 mm.
