Figure 1. PRL decreases anterior pituitary cell proliferation in vivo.

Ovariectomized rats (n = 4 rats/group) were injected with oPRL (1 mg/kg, 6 h) or saline and BrdU (50 mg/kg, 6 h). Proliferation rate was determined by the detection of BrdU incorporation and FACS analysis. Each column represents the mean ± SEM of the percentage of BrdU-positive cells. *p<0.05 vs. respective control (CTRL) animals injected with vehicle, Student's t test.
