摘要
目的:了解和探讨巨噬细胞集落刺激因子(MCSF)及其受体对喉鳞状细胞癌细胞株(Hep2)细胞系的作用。方法:使用氚标记胸腺嘧啶核苷(3HTDR)掺入法和MTT法测试MCSF作用于Hep2后细胞的增殖状况,并测试加入巨噬细胞集落刺激因子受体(MC-SFR)抗体后细胞生长情况。ELISA法测试M-CSF作用Hep2细胞后上清中的MCSF的浓度变化。结果:Hep2细胞培养后较培养前的上清中的MCSF的浓度升高。加入的M-CSF浓度越大,细胞增殖越差,加入MCSFR抗体浓度越大细胞增殖越好。结论:MCSF对喉癌细胞Hep2细胞的增殖具有抑制作用。
Objective:To investigate the possible role of M-CSF and its receptor in the laryngeal carcinoma Hep-2 cell line.Method:Cell proliferation was assayed by MTT analysis and thymidine incorporationx,after Hep-2 cell line culturing with M-CSF and M-CSFR.M-CSF concentration of surpernatant measured by a ELISA technique. Immunohistochemistry was performed on Hep-2 cell line and laryngeal carcinoma tissue.Result:The concentration of M-CSF increased after cell culturing.M-CSF can reduced the Hep-2 cell count.The action can be blocked by Anti-M-CSFR.Conclusion:Our observations support the hypothesis that M-CSF may inhibit the growth and differentiation in Hep-2 cell line.
