Immunocytochemical expression of CK19 in HPV OSCC cell line (SCC-131) and in HPV+ OSCC cell line (SCC-154). The two cell lines were both positive to CK19 antibody but showed a different level of expression. a. Note that the UPCI-SCC-131 cell line showed a lower level of expression, with mostly moderate, focally strong intensity of the staining. b. UPCI-SCC-154 cell line had a higher level of expression, characterized by strong intensity and a diffuse pattern. (LSAB-HRP, nuclear counterstaining with haematoxylin; original magnification, x200)
