Progesterone receptor immunoreactivity in male and female dentate gyrus. Representative image of (A) rostral dentate gyrus and (B) middle dentate gyrus highlighting regions of interest where PR was quantified (gc (granule cell layer), hi (hilus), imol (infrapyramidal molecular layer), slm (stratum lacunosum moleculare), smol (suprapyramidal molecular layer)) (scale bar = 500 μm). (C) The mean number of progesterone receptor immunoreactive (PR-ir) cell nuclei in the rostral and middle infrapyramidal and suprapyramidal blades of the outer molecular layer of the dentate gyrus (DG) of male (N = 23) and female (N = 23) rats at postnatal day 7.
