<p>To compare two sphere scoring parameters of the SSS vs. “number of spheres”, H1299 (2000 cells per well) were plated in 24-well ULA plates in TS medium supplemented with indicated drugs or vehicle for 4 days. %SSS<sub>i</sub> and %n<sub>i</sub> were then calculated. Concentration of drugs were as the following: (A) CI-1033: + 2 μM; (B) Erlotinib: + 3 μM, ++ 6 μM, +++ 10 μM; (C) MK2206: + 0.25 μM, ++ 0.5 μM, +++ 1 μM; (D) Perifosine: + 1 μM, ++ 3 μM, +++ 5 μM; and (E) BEZ235: + 25 nM, ++ 125 nM, +++ 250 nM. The results were presented as Mean ± SEM.</p
