Fig 3. H&E staining of subcutaneous-induced xenograft tumors in athymic Nude-Fox1nu mice.
Tumors were induced by injecting A549-hNIS cells that were genetically modified with either plasmid or lentiviral vectors. Mice were sacrificed at 47 days post tumor cell inoculation. An H&E tumor section of the lung is shown resulting from: A) A549 control tumor; no genetic modification. B) A549-pDNA 1 tumor. C) A549-pDNA 2 tumor. D) A549-LV tumor. (n = 3; all sections shown at 20x magnification; representative images shown)
