Effect of the Uncaria tomentosa (Ut) aqueous extract on the viability of C2C12 myoblasts. Cells were incubated, for 24 h, with the Ut aqueous extract (10, 50, 100, 250, 500, 750 and 1000 μg/ml) and evaluated by the MTT method. The data are presented as the mean ± SE of four individual experiments in triplicates. The values are expressed as the percentage in relation to the control. * Indicates difference in comparison to the control without the Ut extract (p < 0.05)
