Immunolocalization of antigens in cells requires simultaneous preservation of structure and antigenicity. The difficulties of immunolocalization methods are centered around the methods used to preserve structure, which as a rule tend to degrade the ability of antigens (usually proteins) to be recognized by their cognate antibodies. The value of immunolocalization for cell biology was early reco...

The increase intransplacental exchange depends primarily on the great development of the placental vascular bed. The aim of this study was to evaluate the pattern of placental vascular development at day 50 and 100 of pregnancy in goats and the relationship with the vascular endothelial growth factor (VEGF) immunolocalization. The placental morphometric variables: capillary area density, capill...
