BACKGROUND AND AIM Green fluorescent protein (GFP) is a widely used molecular tag to trace transplanted cells in rodent liver injury models. The differing results from various previously reported studies using GFP could be attributed to the immunogenicity of GFP. METHODS Hepatocytes were obtained from GFP-expressing transgenic (Tg) Lewis rats and were transplanted into the livers of wild-type...

background: liver fatty acid-binding protein (l-fabp) is the main cytosolic binding site for long chain fatty acids in hepatocytes. fabps enhance the uptake of fatty acids into the cell by increasing their concentration due to decreasing concentration of unbound fatty acids inside the cell. objectives: the aim of this study was to evaluate the effects of dietary unsaturated to saturated fatty a...

BACKGROUND The size of organs and tissues is basically determined by the number and size of their cells. However, little attention has been paid to this fundamental concept. The liver has a remarkable ability to regenerate after surgical resection (partial hepatectomy [PHx]), and hepatocytes account for about 80% of liver weight, so we investigate how the number and size of hepatocytes contribu...

When parenchymal hepatocytes isolated from adult liver are co-cultured with other epithelial cells, the production of various plasma proteins by the hepatocytes is preserved for much longer than in conventional culture. This study examines some of the metabolic interactions between parenchymal hepatocytes and epithelial cells maintained in co-culture. The leakage of lactate dehydrogenase by hep...

To analyze mechanisms of liver repopulation, we transplanted normal hepatocytes into syngeneic rats deficient in dipeptidyl peptidase IV activity. When isolated hepatocytes were injected into splenic pulp, cells promptly migrated into hepatic sinusoids. To examine whether transplanted hepatocytes entered liver plates and integrated with host hepatocytes, we analyzed sharing of hepatocyte-specif...

Primary cultures of adult mouse hepatocytes are shown here to reexpress differentiated hepatocyte features following treatment with 2% DMSO and 10(-7) M glucagon. To examine the roles of gap junctional communication during hepatocyte growth and differentiation, we have compared treated and untreated hepatocytes from connexin (Cx)32-deficient [Cx32 knockout (KO)] and wild-type mice. In untreated...

The current study included the use of (48) white male laboratory rats, where rats were divided into six groups, with 8 in each group. second group a concentration 30 mg/kg, third 40 fourth 50 and fifth 60 mg/kg nano graphene oxide. sixth is control results statistical analysis showed significant decrease average body weight. On last day experiment when comparing between treated liver weight gro...

We have investigated the effect of a therapeutic agent for liver disease, Laennec, on the GOT leakage from freshly isolated and primary cultured rat hepatocytes which were treated with CCl4. By treatment with Laennec together with CCl4, the GOT leakage from isolated hepatocytes increased and that from cultured hepatocytes decreased, compared to those incubated only with CCl4. The results sugges...

BACKGROUND Many studies have suggested that the immune response may play a crucial role in the progression of hepatocellular carcinoma (HCC). Therefore, our aim was to establish a (i) functional culture of primary human tumor hepatocytes and non-tumor from patients with hepatocellular carcinoma (HCC) and (ii) a co-culture system of HCC and non-HCC hepatocytes with autologous peripheral blood mo...

BACKGROUND In farm animals, there is no suitable cell line available to understand liver-specific functions. This has limited our understanding of liver function and metabolism in farm animals. Culturing and maintenance of functionally active hepatocytes is difficult, since they survive no more than few days. Establishing primary culture of hepatocytes can help in studying cellular metabolism, ...
