Abstract:
Objective To explore the expression of CD133 and nestin in human glioma cell of patients with neuroglioeytoma and to see whether CD133 and nestin expression associate with the differentiation and pathologic grading.Methods The expression of CD133 and nesfin was detected by immunohistochemistry staining in 65 cases of human glioma and 19 specimens of normal brain tissues.Results The rate of the CD133 positive ceUs was 18.46%in human glioma and 0 in the control group(P＜0.01),and that of nesfin was 23.79%and 5.16%respectively.The positive cell rates of CD133 or nestin varied accordingly to different pathological grades.There were significant difference between grade Ⅰ and grade Ⅲ or grade Ⅳ (P＜0.01).There were difference between grade Ⅱ and grade Ⅲor grade Ⅳ (P＜0.01).The same significance were also found between grade Ⅲ and grade Ⅳ(P＜0.01).The higher pathological grades had higher positive cell rates.There was a significant corl~lation between the rate of CD133 positive cells and that of nestin in experimental group (r=0.408,P＜0.01).Conclusion Detecting CD133 and nestin in the human glioma can be used in diagnosing,judging the malignancy degree and the prognosis.
