| Outline of Final Research Achievements |
In this study, we isolated 11 long culture-tumorspheres (LC-TS) from 56 glioma tissues and examined their cellular and genetic properties to examine niche involved with survival, proliferation, and maintenance of undifferentiated state of glioma stem cells (GSC). It was shown that histological (WHO grade4, recurrent, and secondary tumors), and genetic (wild IDH1/2 and TP53, telomerase reverse transcriptase promoter mutation, O-6-methylguanine-DNA methyltransferase (MGMT) promoter hyper methylation, and antigen X-positive) features of tumors were concerned with efficiency of LC-TS establishment. It was also revealed that each LC-TS had different in vivo tumorigenicity, and suggested that it might be caused by difference of some gene expression. It is concluded that these findings will contribute to well understanding of GSC biology.
