From: Two predominant MUPs, OBP3 and MUP13, are male pheromones in rats
Male urine treated with rOBP3 induced c-Fos expression in females. The c-Fos-ir cells were distributed in the AOB (a) and higher brain areas (d). (b), (c) and (e) showed the statistical analyses of the number of c-Fos-ir cells in different brain regions (n = 6, mean ± SE, **P < 0.01, *P < 0.05, independent-sample t-test for five brain areas, AOB, aAOB and pAOB between the PBS-treated control and experimental groups; paired t-test or Wilcoxon signed-rank test for aAOB and pAOB in PBS-treated control or experimental rats. Scale bars = 25 μm)
