FGF2 and central nervous system cancer: Using in vitro cell culture combined with microarray gene expression analysis, we demonstrated that FGF2 dependent glioma cell growth was concomitant with maintained expression of a subset of gliogenic genes, including PDGFRA. Clinically, enriched PDGFRA expression in low- as well as in high-grade glioma samples was associated with younger age at disease onset and better survival outcome of patients.
