Fig. 1From: Cytokeratin7 and cytokeratin19 expression in high grade cervical intraepithelial neoplasm and squamous cell carcinoma and their possible association in cervical carcinogenesisExpression of CK7 and CK19 in non-neoplastic cervix. HE staining shows the transformation zone and SCJ cells (arrow) (a). Strong CK7 staining is seen in the columnar cells at the SCJ with faint staining of CK7 in the squamous cells at the transformation zone (b). Weak staining of CK19 is seen in the columnar cells at the SCJ and the squamous cells at the transformation zone (c). Original magnifications: x400Back to article page
