Study of [18F]FLT and [123I]IaraU for cellular imaging in HSV1 tk-transfected murine fibrosarcoma cells: evaluation of the tracer uptake using 5-fluoro, 5-iodo and 5-iodovinyl arabinosyl uridines as competitive probes.
The inhibitory effects of the VEGFR-1 mutants and the full length VEGFR-1 in BFS-1 fibrosarcoma were mediated through host tumor endothelial cells because the BFS-1 fibrosarcoma cells were not infected by the retrovirus.
