DCA affects clonogenic activity of PTJ64i and PTJ86i cell lines. (A) Representative plates of colony formation assays for both PGL cell lines are shown; (B) Histograms show the means ± SD of three independent experiments (*p < 0.05; ***p < 0.001). PE: plating efficiency [(# of colonies formed/# of cells plated)*100]; SF: surviving fraction [# of colonies formed *100/(# of cells plated *PE of control vehicle)].
