Fig. 3. Effect of MeOH extract from GLE on cell viability of 3T3-L1 cells during postconfluent mitotic clonal expansion. Cells were treated with GLE (5, 25, 50, and 100 µg/mL) or DMSO (control) with MDI differentiation medium at D0. After 24, 48, and 72 h of treatment, viability was measured by MTS assay.

GLE, guava leaf extract; DMSO, dimethyl sulfoxide; MTS, 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium.

^a-cMeans without the same letter are significantly different, as determined by analysis of variance followed by Duncan's test (P < 0.001).
