BACKGROUND: Basic research on HPV has focused on identifying the genetic changes that lead to cervical carcinoma. However, while focusing on the molecular biology of the cancer, understanding of its cellular biology has lagged: the target cell of the HPV infection is unknown. MATERIALS AND METHODS: In this study we identified the stem cell population of the cervical epithelium by monoclonal antibodies against p63, a homologue of the tumor suppressor gene p53 and cytokeratin 17 (CK17). RESULTS: We noted p63 expression consistently in the nuclei of reserve cells, hyperplasia of the reserve cells and the basal layer of the ectocervical epithelium, while CK17 only stained endocervical reserve cells and reserve cell hyperplasia. CONCLUSION: We conclude that both p63 and CK17 are suitable markers for cervical stem cell identification. Both markers, therefore, qualify for the identification of the HPV target cell.
