Fig. 4. Colony Formation and Combination Indices Following Pre-treatment of Igrov1/T8 Cells with TPT and ABCG2 Inhibitors.

Fig. 4

Igrov1/T8 cells were pre-treated with varying concentrations of TPT and 177 (A), 724 (B), or 505 (C) for 48 hours. The cells were then plated on agar and incubated. After 14 days, the colonies consisting of 20 or more cells were counted (n = 3). The combination index values for each combination were calculated (D).
