Measuring Effect of DHA on intracellular accumulation of Pal inside HUVECs evaluated by Oil Red O staining (a). The addition of DHA to the culture medium could decrease the intensity of Pal inside HUVECs. The presence of Pal acid appears a red-colored appearance. MTT assay (b). MTT assay showed that Pal decreased HUVECs viability compared to the control group. The addition of DHA and insulin increased cell survival rate and closed to near-to-control levels (n = 3). One-Way ANOVA and Tukey posthoc analysis. *p < 0.05; and **p < 0.01
