Effects of Mating and Social Exposure on Cell Proliferation in the Adult Male Prairie Vole (Microtus ochrogaster)

Figure 7

Representative photomicrographs of immunolabeling for BrdU (red; (a, c, e, h)) and double immunolabeling for BrdU/DCX (red/green; (b, d, f, i)) from the DG of the control (C), social exposure to a female (SE m/f), social exposure to a male (SE m/m), and social cohabitation with mating (SCM) animals. White arrowheads point to single BrdU-positive cells, and white arrows indicate clusters of BrdU/DCX-positive cells. Scattered squares: enlargements of the inserts at 20x, which show clustering of proliferating neuroblasts observed in the DG from the SE m/f and SCM voles. sp: suprapyramidal blade; ip: infrapyramidal blade. 20x. Scale bar: 100 μm.
