Evaluated apoptosis rate in tumors after treatment in each group by flow cytometry. In both groups containing the reovirus (Reo and Msc-Reo groups), the rate of early apoptosis is higher than the control group, but late and total apoptosis are more significant in the groups containing mesenchymal stem cells. (*: P ≤ 0.05; **: P ≤ 0.01; ***: P ≤ 0.001)
