BACKGROUND Hepatocyte and keratinocyte growth factors are key growth factors in the process of alveolar repair. We hypothesized that excessive alveolar destruction observed in lung emphysema involves impaired expression of hepatocyte and keratinocyte growth factors or their respective receptors, c-met and keratinocyte growth factor receptor. The aim of our study was to compare the expression of...

Abstract Background Domestic cats rarely develop hepatocellular carcinoma. The reason for the low prevalence is unknown. Reductions in ploidy have been associated with hepatic carcinogenesis. Recent work mice has shown that livers more polyploid hepatocytes are protected against development of Hepatocyte domestic cat not evaluated. We hypothesized would be reduced peri-tumoral and neoplastic co...

Prostaglandins (PGs) are known to have effects on hepatic glucose metabolism. Some actions of PGs in intact liver systems may not involve PG effects directly at the level of the hepatocyte. To define the ability of structurally distinct prostaglandins to affect hepatocyte metabolism directly, the regulation of glycogenolysis was studied in hepatocytes isolated from male Sprague-Dawley rats. PGF...

In this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hBMSCs) into hepatocytes on a three-dimentional (3D) nanofibrous scaffold formed by Poly (ε-caprolactone) (PCL), collagen and polyethersulfone (PES). The nanofiber was prepared by the electrospining technique. HBMSCs were isolated using combining gradient density centrifugation ...

Hepatocyte spheroids mimic many in vivo liver-tissue phenotypes but increase in size during extended culture which limits their application in drug testing applications. We have developed an improved hepatocyte 3D spheroid model, namely tethered spheroids, on RGD and galactose-conjugated membranes using an optimized hybrid ratio of the two bioactive ligands. Cells in the spheroid configuration ...

Clinical hepatocyte transplantation is hampered by low engraftment rates and gradual loss of function resulting in incomplete correction of the underlying disease. Preconditioning with partial hepatectomy improves engraftment in animal studies. Our aim was to study safety and efficacy of partial hepatectomy preconditioning in clinical hepatocyte transplantation. Two patients with Crigler-Najjar...

BACKGROUND Orthotropic liver transplantation (OLT) is the final procedure of both end stage and metabolic liver diseases. Hepatocyte transplantation is an alternative for OLT, but the sources of hepatocytes are limited. Bone marrow mesenchymal stem cells (BM-MSCs) can differentiate into hepatocyte-like cells and are a potential alternative source for hepatocytes. We aimed to investigate the dif...

background: the radioprotective effect of grewia asiatica fruit (gae) which contains anthocyanin type cyanidin 3- glucoside, vitamin c, a, minerals, carotenes and dietary fibers etc was studied. materials and methods: for study swiss albino mice were divided into five groups-1. control (vehicle treated) 2. gae treated (700 mg / kg. b.wt / day for fifteen days), 3. irradiated (5 gy), 4. gae + ir...
