ABSTRACT

Objective To identify and isolate the CK17+,CD44v5+ and Bcrp1+ cells in HeLa cells,and investigate the relationship between them and select cervical cancer stem cell markers.Methods Flow cytometry was used to identify and isolate the CK17+,CD44v5+ and Bcrp1+ cells in HeLa cells;after isolation,the expressions of CK17 and CD44v5 in Bcrp1+ and Bcrp1-phenotype HeLa cells were measured by immunocytochemistry.Results HeLa cells contained 11% Bcrp1+ cells,0.7% CK17+ cells and 0.1%CD44v5+ cells.Bcrp1+ HeLa cells contained CK17+ and CD44v5+ HeLa cells,but the Bcrp1-Hela cells did not(P
