Hypothalamic target cells of endogenous sexual steroids in female rat. An immunocytochemical approach utilizing antiestradiol antiserum.
The immunostaining proposed in this study identifies cells containing endogenous estrogens in the Central Nervous System, in the presence of both very high and very low serum estrogen levels. Ten adult rats, seven normal and three ovariectomized females, were used for this study. Paraffin sections of hypothalamus and ovary of each female were stained using Avidin-Biotin Complex method and antiestradiol antiserum. Two different antiestradiol antisera were tested in this work: tests for method and antisera specificity are described. The immunostaining used here shows to be specific and sensitive revealing a higher number of labeled hypothalamic areas than those revealed by other techniques.
