Figure 1From: Shikonin suppresses ERK 1/2 phosphorylation during the early stages of adipocyte differentiation in 3T3-L1 cells Effect of shikonin on the lipid accumulation of 3T3-L1 adipocytes. (A) Cell viability was determined by an MTT assay. (B) The lipid content was assessed by Oil Red O staining. (C) The absorbance of Oil Red O dissolved in isoprophanol was spectrophotometrically determined at 500 nm.Back to article page
