Cellular heterogeneity and therapeutic response profiling of human IDH + glioma stem cell cultures.

ABSTRACT: Glioblastoma stem cell (GSC) cultures are initiated from glioblastoma (GBM) surgical resection tissue. When grown appropriately they can capture and propagate key GBM molecular and cellular features. We have characterized cellular, genomic and proteomic features of four isocitrate dehydrogenase (IDH)-expressing (IDH +) GSC cultures as cellular models for ~ 90% of adult GBMs. We demonstrate that GSC cultures can be continuously propagated in defined, serum-free media and 5% oxygen without specialized growth substrates; have culture-specific genomic and mtDNA variants together with gene/protein expression profiles; and display reproducible dose-survival curves for the GBM standard-of-care therapies ionizing radiation (IR) and temozolomide (TMZ). In order to better define GSC culture cellular
