MTT assay detected cell viability of tumor cells and normal cells infected with increasing MOIs of recombinant oncolytic adenovirus. A.Tumor cells were infected with ONYX-015, AD55 and AD55-Apoptin at the increasing MOIs (0.1, 1, 10), after 4 days, cell viability was determined by MTT assay. B. Cell viability of normal cells (L-02, WI38, QSG-7701) infected with the above three different viruses, Datas were shown as means ± SD (error bars) of triplicate experiments,* p < 0.05, compared with the AD55 treatment group.
