Figure 3. Omipalisib has a superior impact on the clonogenicity of NCM cells. (A) Scheme of experiment. (B) Representative pictures of colony formation 5 days post seeding. Scale bar represents 100 μm. (C) Graphs showing relative impact of each drug compared to vehicle on colony formation. Total number of colonies, surviving fraction as well as viability was estimated. *p<0.001 (one-way ANOVA). Plating efficiency and surviving fraction was calculated according to Franken et al. (23).
