Background Adipose tissue mesenchymal stem cells (AT-MSCs) are suitable choices in treatment of liver associated diseases. Dimethyl Sulfoxide (DMSO) is an amphipathic molecule with potential of delivering both lipophilic and hydrophilic agents into cells. Few protocols used DMSO for induction of AT-MSCs towards hepatocyte like cells but the effect of DMSO on hepatogenic differentiation were no...

Often results from toxicological studies using rodent models cannot be directly extrapolated to probable effects in human beings. In order to examine the genotoxic potential of chemicals in human liver cells, a human hepatocyte DNA repair assay has been defined. Procedures were optimized to prepare primary cultures of human hepatocytes from discarded surgical material. On eight different occasi...

The phosphorylation of rat liver pyruvate kinase was studied in isolated rat hepatocytes and with the crystalline enzyme. Hepatocytes were incubated with ["PI orthophosphate and isotopically labeled pyruvate kinase was quantitatively isolated using a resin-coupled antibody. The molar extent of phosphorylation of the enzyme was calculated from the amount of radioactivity in the enzyme and the sp...

In order to examine the genotoxic potential of chemicals in human liver cells, a human hepatocyte DNA repair assay has been defined.

Introduction: To investigate the nonlinear kinetics of in vitro hepatic uptake the OATP substrate, Pitivastatin, was used as a probe. Experiments were conducted using freshly isolated rat hepatocytes, utilising the ‘oil spin’ methodology described by Hassen et al [1]. Briefly, freshly isolated rat hepatocytes were incubated with Pitvastatin (5–300μM). At 10 s, 30 s, 50 s and 70 s aliquots were ...

To understand regulation of transplanted hepatocyte proliferation in the normal liver, we used genetically marked rat or mouse cells. Hosts were subjected to liver injury by carbon tetrachloride (CCl4), to liver regeneration by a two-thirds partial hepatectomy, and to hepatocellular DNA synthesis by infusion of hepatocyte growth factor for comparative analysis. Transplanted hepatocytes were doc...

Methimazole is used as an antithyroid drug to control the symptoms of hyperthyroidism and maintain patients in a euthyroid state. Administration of this drug is associated with agranulocytosis and hepatotoxicity, which are the two most significant adverse effects. The present investigation was conducted to study the protective role of taurine against cytotoxicity induced by methimazole and its ...

Due to the time-dependent loss of cytochrome P450 (P450)-mediated metabolism in freshly isolated hepatocytes, several types of culture systems have been developed to extend their lifespan. The aim of this study was to evaluate the ability of monolayer cultures of rat hepatocytes to determine the in vitro CL(int) compared with suspensions of freshly isolated hepatocytes. Seven compounds were inc...

Hepatocyte function is regulated by several P2Y receptor subtypes. Here we report that 2-methylthioadenosine 5'-diphosphate (2-MeSADP), an agonist at P2Y(1), P2Y(12), and P2Y(13) receptors, potently (threshold 30 nM) stimulates glycogen phosphorylase in freshly isolated rat hepatocytes. Antagonism by N(6)-methyl 2'-deoxyadenosine 3',5'-bisphosphate (MRS 2179) confirms that this response is medi...
