[Immunocytochemical localization of estrogen receptor in the oogenesis of termites].
The expression of estrogen receptor(ER) was examined in the oogenesis of termites (Reticulitermes aculabialis) with immunocytochemical localization method. The results showed ER existed in oocytes at the process of differentiation and the process of growth. ER immunopositive substance was localized in the nucleus of oocytes at the differentiation stage and (the cytoplasm of oocytes at the growth stage. On the other hand,previous studies have demonstrated the procerebrum of termites could secrete FSH (Follicle Stimulating Hormone)and LH (Luteinizing Hormone) which stimulated estrogen secreting. These results provide a new morphological proof that "brain-gonad" participates in the regulation of the oogenesis of termites, as have been shown in mammal.
