Figure 1. Generation of PTEN wt and PTEN null gliomas using the RCAS/tv-a system.

Figure 1

(A) Four-to-six week old nestin-tv-a/ink4a-arf-/-/ptenfl/fl mice are stereotactically injected with DF-1 cells expressing the RCAS-PDGF-B virus and from high-grade gliomas with PTEN intact. (B) Four-to-six week old nestin-tv-a/ink4a-arf-/-/ptenfl/fl mice are stereotactically injected with DF-1 cells expressing the RCAS-PDGF-B virus and DF-1 cells expressing RCAS-Cre virus and from high-grade tumors with PTEN deleted.
