Topography of the neurons responding to estrogen in the hypothalamic arcuate nucleus of immature female mice.

The neurons in the hypothalamic arcuate nucleus (ARC) of 20-day-old female mice were examined by electron microscopy. The administration of estradiol-17 beta during 20 days from the day of birth resulted in the increase of dense-core vesicles (DCVs) in some neuronal perikarya of the middle region of the ARC (middle ARC), while, in the posterior region of… CONTINUE READING
