Inhibition of colony formation of EGCG in a dose-dependent manner. Both TW01 and TW06 sphere-derived cells were treated with 20 μM or 40 μM EGCG and performed colony formation assay. Decreasing colony number are noted when EGCG concentration increasing. Data represent mean ± SD. * or # means significantly different from respective controls, p < 0.05.
