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

Figure 4

Representative photomicrographs of double immunolabeling for BrdU and DCX in the RMS subareas (red/green; (a, e, i, m); photomicrographs were taken at 20x, scale bar: 500 μm). Representative photomicrographs (20x, scale bar: 100 μm) of the anterior, medial, and posterior subareas of the RMS. Control (C; (a–d)), social exposure to a female (SE m/f; (e–h)), social exposure to a male (SE m/m; (i–l)), and social cohabitation with mating (SCM; (m–p)). A scattered square (panel C) represents enlargements of the inserts. White arrows indicate BrdU-positive/DCX-positive cells organized in chain arrangements, and arrowheads point to BrdU-positive/DCX-negative cells. a: anterior; m: medial; p: posterior.
