Protein expression of PV-1 in GEnC of immature glomeruli. In the S-shaped body (A through A″), capillary loop (B through B″), and maturing glomerulus (C through C″) stages, the immunoreactivity for PV-1 (red) is found in almost all GEnC, which are visualized by the anti–ICAM-2 antibody (green); however, most of the GEnC in adult rat do not exhibit immunoreactivity for PV-1 (D through D″). Arrowheads, vascular cleft. Bar = 25 μm.
