Fig. 6From: Anti-adipogenic and anti-obesity activities of purpurin in 3T3-L1 preadipocyte cells and in mice fed a high-fat dietEffect of purpurin on lipid accumulation in differentiated 3T3-L1 cells as measured with Oil Red O staining. The accumulation of lipid was evaluated: a microscopically; and (b) colorimetrically (absorbance at 520 nm) from solubilized fat droplets collected from the stained cells. Data are expressed as the mean ± SD of triplicate experiments. Bars sharing a common letter are not significantly different at p < 0.05Back to article page
