Effects of GA on the viability of oral squamous cell carcinoma cell lines. a: Three oral squamous carcinoma cell lines were treated with 0, 2, 3, 4, 5 and 6 μM of GA for 24 hours, 48 hours and 72 hours. The inhibitory effects of GA were shown in a time- and dose-dependent manner. b: Morphological changes of Tca8113 cells under phase contrast microscopic observation induced by 4 μM GA from 0 to 72 hours. (A: 0, B: 24 hours, C: 48 hours, D: 72 hours, 100×, original magnification).
