| 摘 要： | 目的：探讨胶质瘤中肿瘤干细胞标志物CD133的表达及其与p53、MGMT的关系。方法：采用免疫组化法检测45例不同病理级别胶质瘤标本中CD133和p53、MGMT蛋白的表达。结果：CD133在各病理级别的胶质瘤中均有表达,高恶性度组中CD133表达高于低恶性度组（P〈0.05）。在CD133阳性组中p53、MG-MT的表达明显高于CD133阴性组（P均〈0.05）。结论：不同恶性程度的胶质瘤标本中均存在肿瘤干细胞,肿瘤干细胞可作为判断胶质瘤恶性程度和预后的重要指标。

| Abstract: | Objective：To investigate the expression of tumor stem cell marker CD133 in glioma tissues and the relationship with p53 and MGMT.Methods：Expressions of CD133,p53 and MGMT in 45 cases of glioma tissues were detected by immunohistochemcal method.Results：CD133 could be observed in glioma tissues,and there was a significant difference between the expression of CD133 in high malignant gliomas and that in lowmalignant gliomas（P0.05）.The differences of p53 and MGMT expressions were statistically significant in the CD133-positive glioma group and the CD133-negative glioma group（P0.05）.Conclusion：Tumor stem cell could be detected in glioma,and can serve as an important marker in evaluating glioma malignancy and prognoses. |
