Replacement of Retinyl Esters by Polyunsaturated Triacylglycerol Species in Lipid Droplets of Hepatic Stellate Cells during Activation
Figure 5
HSC activation results in a preferential decrease in retinyl esters.
A. Neutral lipid composition of quiescent HSCs (day 0) analyzed by HPLC-APCI-MS. The results represent the means ± SEM of three experiments. B. Quantification of RE, cholesterol esters (CE), total TAG (TAG), and TAG(18:2,18-2,18:2) content in HSC at day 0, 4 and 7. Values are expressed relative to the level of lipid present at day 0. The results represent the means ± SEM of three experiments.
