Cytotoxicity of NV1066 on mesothelioma cells. Eleven mesothelioma cells, epithelioid (H-2452, H-Meso), sarcomatoid (VAMT, H-28, H-2052, H-2373), biphasic (H-Meso1A, MSTO-211H, JMN) and miscellaneous (Meso-9 and Meso-10) were infected in vitro with NV1066. In all these cell lines, NV1066 was cytotoxic at all MOIs of 1 (A), 0.1 (B) and 0.01 (C). Cell kill was represented as percentages of live cells compared to control untreated cells grown under identical conditions. MOI = Multiplicity of infection, ratio of viral particles to tumor cells.
