The successful encapsulation of human hepatocellular carcinoma (HepG2) cells would assist applications in tissue engineering. In this paper, we have developed a method to produce chitosan-alginate microfibers within a microfluidic chip. Also, by suspending cells in the mixing solution, we fabricated HepG2 cell-laden fibers. The encapsulated HepG2 cells in the chitosan–alginate fibers were more ...

In this paper, we demonstrate formation of size-controlled 3-dimensional hetero-spheroids using a micro-fluidic device in approximately 2 min. The device collects cells in the center of a micro-chamber using micro-rotational flow as shown in Fig. 1. In previous work, we used this device to generate size-controlled HepG2 spheroids [1]. We applied it to form heterospheroids consisting of HepG2 an...

Hepatoma cells derived from liver carcinoma are a candidate cell source for bioartificial (BAL) systems due to their high proliferative capacity, although function of hepatoma is considerably low compared with primary hepatocytes. In our previous study, genetically engineered mouse inducible were established by transducing liver-enriched transcription factor (LETF) genes. this we aimed develop ...

Accumulating evidence indicates that Nanog plays a central role in modulating the biological behaviors of human hepatocellular carcinoma (HCC). However, the underlying mechanisms remain unclear. In the present study, we employed transcription activator-like effector nucleases (TALEN) to disrupt Nanog expression in HepG2 cells and obtained subcloned cells with diallelic Nanog mutations. Signific...

The primary reservoir for hepatitis C virus (HCV) replication is believed to be hepatocytes, which are highly polarized with tight junctions (TJ) separating their basolateral and apical domains. HepG2 cells develop polarity over time, resulting in the formation and remodeling of bile canalicular (BC) structures. HepG2 cells expressing CD81 provide a model system to study the effects of hepatic ...

Primary human hepatocytes (PHH) are a main instrument in drug metabolism research and in the prediction of drug-induced phase I/II enzyme induction in humans. The HepG2 liver-derived cell line is commonly used as a surrogate for human hepatocytes, but its use in absorption, distribution, metabolism, and excretion and toxicity studies can be limited because of lowered basal levels of metabolizin...

Fatty acid synthase (FAS; EC 2.3.1.85) was purified to near homogeneity from a human hepatoma cell line, HepG2. The HepG2 FAS has a specific activity of 600 nmol of NADPH oxidized per min per mg, which is about half that of chicken liver FAS. All the partial activities of human FAS are comparable to those of other animal FASs, except for the beta-ketoacyl synthase, whose significantly lower act...

Hepatocellular carcinoma and glioblastoma are both very aggressive forms of human neoplasms. The most effective treatment includes the combination of surgery, chemotherapy and radiation. Sodium butyrate (NaB) demonstrates a high efficiency and low toxicity. It inhibits proliferation and cell cycle of the cancer cells. The aim of this study was to investigate the effect of sodium butyrate on Hep...

The present study aimed to determine the cytotoxicity of microcystin-LR (MC-LR) on the human hepatocellular carcinoma (HepG2) cells in order to elucidate the mechanism of apoptosis induced by MC-LR. Morphological evaluation results showed that MC-LR induced time- and concentration-dependent apoptosis in HepG2 cells. The biochemical assays revealed that MC-LR-exposure caused overproduction of re...
