We have used a combined biochemical and morphological approach to establish the suitability of certain endogenous and exogenous domain markers for monitoring the separation of rat hepatocyte plasma membrane domains in sucrose density gradients. As endogenous domain markers, we employed two of the integral plasma membrane protein antigens, HA 4 and CE 9, localized to the bile canalicular and sin...

CONTEXT Hepatocyte transplantation is an attractive therapeutic modality for liver disease as an alternative for orthotopic liver transplantation. OBJECTIVE The aim of the current study was to investigate the feasibility of freshly isolated rat hepatocyte transplantation in acetaminophen-induced hepatotoxicity model. METHODS Hepatocytes were isolated from male Wistar rats and transplanted 2...

In this research, we investigated the cytotoxic mechanisms of Cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.This micro algae is responsible for a severe and widespread harmful algal bloom in the Persian Gulf and Gulf of Oman (2008-2009). Isolated hepatocytes were obtained by collagenase perfusion of Sprague-Dawley rat liver.According to our results, incubation of algal...

The polarized molecules predominately distributing at hepatocyte canalicular surface play a vital role in disclosing the process of bile formation and etiopathogenisis of cholestatic live diseases. Therefore, it is important to find novel polarized molecules on hepatocyte canalicular membrane. In the present study, canalicular membrane vesicles (CMVs) isolated from rat hepatocyte by density gra...

Isolated rat and human hepatocytes in primary culture were shown to metabolize AAF to reactive intermediates which damaged hepatocyte DNA. A significant increase in unscheduled DNA synthesis was detectable by autoradiography in rat and human hepatocytes exposed to concentrations of AAF as low as 1 microM. When rat hepatocytes were plated over confluent monolayers of human fibroblasts and expose...

Well-established techniques are available to predict in vivo hepatic uptake and metabolism from in vitro data, but predictive models for biliary clearance remain elusive. Several studies have verified the expression and activity of ATP-binding cassette (ABC) efflux transporters central to biliary clearance in freshly isolated rat hepatocytes, raising the possibility of predicting biliary cleara...

The fact that colchicines inhibits hepatic secretion of very low density lipoprotein (VLDL) particles has been interpreted to mean that microtubules are involved in hepatic VLDL secretion. To further define this relationship, we have attempted to see if changes in hepatic VLDL secretion are associated with changes in hepatocyte microtubule or tubulin content. Accordingly, hepatic secretion of V...

The fact that colchicine inhibits hepatic secretion of very low density lipoprotein (VLDL) particles has been interpreted to mean that microtubules are involved in hepatic V L D L secretion. To further define this relationship, we have at tempted to see if changes in hepatic V L D L secretion are associated with changes in hepatocyte microtubule or tubulin content. Accordingly, hepatic secretio...

Recent evidence proposes that cells with the properties of mesenchymal stem cells (MSCs) can be extracted from adult peripheral tissues, including muscle, dermis and adipose tissue. Adipose tissue is ubiquitous and easily obtainable in large quantities. We separated Adipose derived stem cells (ADSCs) from part of subcutaneous adipose tissue from rat. These cells could be readily differentiated ...
