Using terminal deoxynuceotidy transferase mediated dUTP nick end labeling (TUNEL) , apoptotic cells were detected in situ in 40 ECAC specimens, Results:The expression of FasL protein was detected in all 50 ECAC examined.

• 采用脱氧核糖核酸末端转移酶介导的缺口末端标记技术(TUNEL),对50例贲门癌组织中凋亡的TIL及肿瘤细胞进行观察。 结果50例贲门癌组织FasL蛋白表达程度不等。
