In both cases, the MIB-1 staining indices were high for grade I meningioma (5.6% for case 1 and 9.1% for case 2), and abnormal accumulation of p53 were observed by immunohistochemistry.

We can overcome the senescence of a Grade III derived meningioma cell line by expressing the telomerase catalytic subunit (hTERT), whereas Grade I meningioma cell lines require the expression of the human papillomavirus E6 and E7 oncogenes in conjunction with hTERT.
