Dear Editor, Recently, mature hepatocytes have attracted a great deal of attention in drug metabolism or toxicities instead of liver tissue. The human hepatoma cell line, HepG2, was found to chemically differentiate into mature hepatocyte-like cells by sodium (Na) butyrate, and some of the properties of mature hepatocytes were induced by their(More)
We studied the lipoprotein profiles of human hepatic cells at various stages of differentiation. The production of three major classes of lipoproteins, very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), was detected in three well-differentiated human hepatoma cell lines and primary human hepatocytes;(More)
We developed an in vitro screening system for antihyperlipidemic activity by measuring lipoprotein profiles secreted from human intestinal epithelium-like cells from the colon cancer cell line, Caco-2. Sodium (Na) butyrate at 5 mM differentiated Caco-2 cells into intestinal epithelium-like cells and numerous microvilli on the apical side of cells were(More)
