Dimethyl sulfoxide (DMSO) was tested for its effects on lipid metabolism of long-term cultures of adult rat hepatocytes. The addition of 1% DMSO to 3T3-hepatocyte cultures was not toxic to cells and in fact treated cultures maintained better their characteristic morphology for up to 14 days of exposure. DMSO treatment increased 2-3 fold the de novo synthesis of total lipids from[14C]acetate. The analysis by thin layer chromatography of cellular and secreted lipids revealed that DMSO increased the levels of cellular triglycerides, phospholipides and free and sterified cholesterol at 7 days of exposure while at 14 days there was also a 2-3-fold increase in medium secreted lipids. Additionally, DMSO increased the activity of glycerol-phosphate dehydrogenase, a marker enzyme of glycerolipid synthesis, by greater than 50% at either 7 or 14 days of exposure. These results show that 1% DMSO not only is not detrimental to cultured hepatocytes but also enhances lipid synthesis and secretion, both hepatic-differentiated functions.
