Fig. 2

Growth rate after drug combination treatment. Cells were treated with drugs for 3 days and imaged by microscope. Alive cell numbers were extracted from the microscope images and used to calculate growth rate of drug treated cells. Mean values of growth rate were shown as a heatmap (n = 4). Cell numbers ranged from 4000 to 10 s. Drug concentration C1 means the highest concentration and C6 means the lowest concentration. Growth rate 1 means no inhibition and -1 means all death
