Abstract
Abstract We have generated mouse models of GBM by driving loss of function of in the NF1, p53 and Pten tumor suppressors in the adult mouse brain. Using genetic cell labeling and lineage tracing approaches, our models support the hypothesis that stem/progenitor cells are the most likely cells to accumulate mutations over time and become the source of GBM. We have succeeded in reporter labeling the putative “Cancer Stem Cell” population and demonstrate their requirement for effectively mediating endogenous tumor recurrence after chemotherapy and in successfully supporting serial transplantation of tumors in intracranial allografts. The availability of enriched Cancer Stem cells should provide a powerful tool for identifying critical molecular properties and novel therapeutic targets. Citation Format: Luis F. Parada.
