Immunostaining of ER-α and ER-β receptors in human cervical tissues. A. Immunopositivity of ER-α in the normal cervical epithelium showing nuclear reaction mainly in the parabasal layers (X40). B. Immunonegativity of ER-α in invasive carcinomas (X10). C. Immunopositivity of ER-β in normal cervical epithelium showing nuclear and cytoplasmic reaction in the cells of basal and parabasal layers (X40). D. Immunopositivity of ER-β in cervical invasive carcinoma with nuclear and cytoplasmic reaction in epithelial invasion zones (X10). E. A negative control in normal cervical tissue consisted of the omission of the primary antibody (X40). F. Positive control of ER-α in normal breast tissue (X100).
