Anterior pituitary HNr expression in female rats is lower than in males.

<p>Dispersed anterior pituitary cells from intact male and female rats were immunostained for HNr and analyzed by flow cytometry. Each column represents the mean ± SE (n = 4 animals per group) of (A) the percentage of HNr-positive cells, and (B) the fluorescence intensity of HNr staining (Gmean). The upper panels show representative dot plots and histograms of HNr expression in anterior pituitary cells from male and female rats. **p<0.01, Student’s <i>t</i> test.
