CST3 immunolocalization in the cervix. Paraffin sections of the cervix at early (a and b) and late (c) proliferative phases of the menstrual cycle were immunostained using control antibody (a) or anti-CST3 antibody (b and c). The selected region in b and c was enlarged for clarity (d and e). The staining signals were colored brown by the HRP substrate DAB. Symbols: ecto, ectocervix; endo, endocervix; e, cervical epithelium; g, cervical gland; m, cervical mucus. Bars: A–C, 2 mm; D and E, 1 mm
