Abstract Estrogens derived from the aromatization of androgens are believed to be responsible for the induction of the sexual differentiation of the CNS interacting with specific estrogen receptors (ER) present in developing neurons. However, the brain cellular distribution of ER is not so well documented. The aim of this study was to investigate the qualitative and quantitative expression of ER mRNA in well characterized cultures of rat type 1 and type 2 astrocytes and of oligodendrocytes by polymerase chain reaction. A series of amplifications with a set of primers spanning along the entire ER mRNA was utilized in the different types of glial cells, in a positive control (uterus), and in a negative control (SK-N-BE cell line) previously shown to be devoid of ER. The data obtained show that ER mRNA is expressed in all three types of glial cell analyzed in almost equal amounts, which are 25-50 times lower than those in the uterus. The mRNA expressed in the glia is homologous with that expressed in the uterine tissue.
