(A) QH1-stained section of a chick mesonephros grafted onto quail CAM showing a great invasion of QH1-positive cells of host origin: endothelial cells (arrows) that are located around the tubules forming part of the peritubular capillary plexus (p), and macrophages (arrowheads). (B) LEP 100 IgG-stained consecutive section. The endothelial cell (arrows) do not present the LEP 100 epitope and only macrophages (arrowheads) are positive to this antibody. Note the intense reaction of the proximal tubules (t) cells. Scale bar = 18.5 µm.
