摘要:

目的:检测Bcrp1、CK17及CD44v5在宫颈癌HeLa细胞中的表达情况及相互关系,推测该3种抗体成为宫颈癌干细胞标记物的可能。方法:采用免疫荧光标记物流式细胞仪分选并检测HeLa细胞中的CK17+、CD44v5+、Bcrp1+表型细胞;利用免疫细胞化学染色法,检测Bcrp1+ 及Bcrp1-1两组HeLa细胞中CK17及CD44v5的表达情况。结果: HeLa细胞中存在CD44v5+细胞,所占比例为0.1%,CK17+细胞为0.7%,Bcrp1+细胞为11%;Bcrp1+组HeLa细胞中存在CK17+及CD44v5+细胞,而Bcrp1-组中则无,组间比较差异有显著性(P<0.05)。结论:表达CK17及CD44v5的HeLa细胞同时表达Bcrp1转运蛋白,CK17及CD44v5均有可能成为宫颈癌干细胞的标记物。

Abstract:

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<0.05).Conclusion HeLa cells expressed CK17 and CD44v5 antibody must express Bcrp1 antibody.CK17 and CD44v5 may be used as the markers of cervical cancer stem cells.
