Figure 1.

The expression of D2-40 in the normal cervical tissue and CIN. The D2-40 immunoreactivity was localized to the basal cell layer as well as the endothelial cells of lymphatic vessels indicated by arrow. A: diffuse expression of D2-40 in the basal cells of squamous epithelium in the normal cervical tissue. B: diffuse expression of D2-40 in the basal cells of squamous epithelium in CIN1 on the right and foal expression of D2-40 in the basal cells of squamous epithelium in CIN2 on the left. C: negative expression of D2-40 in CIN2. D: negative expression of D2-40 in CIN3 in the middle and diffuse expression of D2-40 in the basal cells of squamous epithelium in the normal cervical tissue indicated by arrow.
