VHR expression and localization in cervix cell lines and primary keratinocytes. A/ Immunochemistry of VHR in primary keratinocytes (a), in HPV positive, HeLa (b), SiHa (c) and CaSki (d) and HPV negative C33 (e) and HT3 (f) cell lines. Brown indicates the VHR specific staining and blue represents the hematoxylin staining of nuclei. B/ Immunofluorescent staining under confocal microscopy of the primary keratinocytes and cancer cell lines HeLa, CaSki, SiHa and C33. Green indicates the VHR specific staining and Red (TOTO-3) staining for the nuclei.
