Abstract Primary hepatocytes are commonly used during in vitro studies, but care must be taken with isolation and culture of the cells to ensure their viability. In this study, hepatocytes were isolated from the liver (caudate process) of a newborn calf by the collagenase perfusion and digestion method. The trypan blue exclusion method was used to determine total cell number and the survival rate of hepatocytes, while hepatocyte function was assessed by measuring lactate dehydrogenase, albumin and urea in culture medium supernatants at 24, 48, 72, 96, 120, 144 and 168 h. Results showed that the number of viable cells/g of liver (wet weight) averaged 1.12 × 10 7  cells/g, with an average hepatocyte viability of 85.7% (range 83–92%). After 48 h of culture, the hepatocytes solidly adhered to the well culture plate and were spread in an epithelioid shape, with clear cell boundaries between the cells and biliary ductule-like structures formed which persisted for up to 10 days. Hepatocyte function was optimal at 72 h after isolation and culture. This simple and economical procedure for the isolation and culture of viable cells may be useful for in vitro bovine hepatocyte studies.

Abstract Fenitrothion, endosulfan and abamectin are insecticides that affect various organs in humans and animals. The present study was conducted to investigate their cytotoxicity in isolated male rat hepatocytes. The study suggests that incubation of hepatocytes with 10 or 100 μM of each insecticide for 2 h significantly decreased the cell viability. Increased leakage percentage of lactate dehydrogenase (LDH), alanine transaminase (ALT) and aspartate aminotranferase (AST) were detected in hepa...

We studied cadmium toxicity in murine hepatocytes in vitro. Cadmium effects on intracellular free Ca 2+ concentration ([Ca 2+ ]i) were assayed, using a laser scanning confocal microscope with a fluorescent probe, Fluo-3/AM. The results showed that administration of cadmium chloride (CdCl 2 , 5, 10, 25 μM) resulted in a dose-dependent decrease of hepatocyte viability and an elevated aspartate aminotransferase (AST) activity in the culture medium (p<0.05 for 25 μM CdCl 2 vs. control). Significant ...

In this work we have studied the isolation and culture of mature bovine hepatocytes on plastic dishes without exogenous matrix. The liver has been disaggregated in a collagenase solution instead of undergoing a perfusion step. After a few days in culture, the plates showed several clusters of different cell types. Although the average yield was 1.60±0.57×108 viable liver cells per gram of tissue, these cultures were formed by non-parenchymal cells and only very few or none by parenchymal cells. ...

In dairy cows, fatty liver is one of the most common metabolic diseases that occurs during the periparturient period. Angiopoietin-like protein 4 (ANGPTL4) is a well-known downstream target of peroxisome proliferator-activated receptors (PPARs), which regulate the glucose and fatty acid metabolisms. The inhibition of lipoprotein lipase (LPL) activity interferes with the storage of triglycerides (TG) in adipocytes, which plays an essential role in lipid metabolism in rodents. However, it remains ...

Abstract Maternal undernutrition during late gestation accelerates body fat mobilization to provide more energy for foetal growth and development, which unbalances metabolic homeostasis and results in serious lipid metabolism disorder. However, detailed regulatory mechanisms are poorly understood. Here, a sheep model was used to explore the regulatory role of PPARA/RXRA signalling in hepatic lipid metabolism in undernutrition based on RNA sequencing and cell experiments. KOG function classificat...

: Dairy cows with fatty liver or ketosis display decreased insulin sensitivity and defects in the insulin receptor substrate (IRS)/PI3K/AKT signaling pathway. Phosphatase and tensin homolog (PTEN) is a well-known tumor suppressor and also a negative regulator of insulin signaling and peripheral insulin sensitivity. We investigated the hypothesis that PTEN may affect the insulin pathway-mediated hepatic glucose and lipid metabolism in dairy cows. Adenovirus vectors that over-express and silence P...

Summary Negative energy balance is considered as the pathological basis of energy metabolic disorders in periparturient dairy cows. Serum non-esterified fatty acids (NEFA) are one of the most important indicators of energy balance status. Fibroblast growth factor 21 (FGF21) has been identified as a hepatokine involved in regulation of metabolic adaptations, such as promoting hepatic lipid oxidation and ketogenesis, during energy deprivation. However, the direct effects of NEFA on FGF21 expressio...

Elevated levels of blood interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumour necrosis factor–α (TNF–α) increase insulin resistance and result in inflammation. It is not clear whether elevated blood level of acetoacetate (ACAC) and decreased blood level of glucose, which are the predominant characteristics of clinical biochemistry in ketotic dairy cows, increase proinflammatory cytokines and subsequent inflammation. The objective of this study was to test the hypothesis that ACAC and glucose ...

Abstract Fatty liver is a major metabolic disorder of dairy cows. One important reason is that hepatic very low-density lipoproteins (VLDL) assembly was significant decreased in dairy cows with fatty liver. In addition, the impairment of insulin-like growth factor (IGF)-1 synthesis was involved in the development of fatty liver. Therefore, the objective of this study was to investigate the effects of IGF-1 on the VLDL assembly in cow hepatocytes. In this study, cow hepatocytes were cultured and ...

β-hydroxybutyric acid (BHBA), an important metabolite in β-oxidation, is involved in the development of ketosis in dairy cows. It is known that AMP-activated protein kinase (AMPK) signaling pathway plays an important role in the regulation of lipid metabolism in hepatocytes. In the present study, bovine hepatocytes were treated with BHBA at variable concontrations and Compound C (Cpd C, an AMPK inhibitor) to investigate the effects of BHBA on the AMPK signaling pathway. The results showed that w...

An elevated plasma non-esterified fatty acids (NEFA) concentration is an important indicator of negative energy balance, which is often associated with metabolic diseases such as fatty liver and ketosis. Angiopoietin-like protein 4 (ANGPTL4) is a hepatokine that plays important roles in the regulation of lipid metabolism. However, the direct effects of high concentrations of NEFA on ANGPTL4 expression and secretion in hepatocytes from cows are not entirely clear. The objective of this study was ...
