Susceptibility of bone tumor cells to H-1PV infection. Primary human osteoblasts and fibroblasts, the human osteosarcoma cell lines U-2 OS, SaOS-2, and MG-63, and the human neuroblastoma cell line WAC-2 were infected with Chi-hH1/EGFP at a multiplicity of infection (MOI) of 0, 1, 10, or 50 RU/cell. Green florescent cells were counted at different times post-infection. Counting was done manually in a pool of 4000 (for cell lines) or 10,000 cells (for primary osteoblasts or fibroblasts) per well.
