Abstract

In this work we have investigated a system of long-term primary cultures of adult human hepatocytes which, in contrast to those previously described, has the advantage of requiring neither the use of additive cells as in co-cultures, nor of matrix component preparations like Matrigel or collagen sandwich. This system has been used previously for long-term cultures of hepatocytes from young baboon, and some modifications have been introduced here to take into account the specificity of adult human hepatocytes. In this system, hepatocytes are plated at confluence on collagen-coated dishes and cultured in a serum-free medium consisting of Williams'E supplemented with hormones and growth factors. Proteins secreted specifically by the liver, including albumin, α-1 antitrypsin, plasminogen, fibrinogen, lipoproteins ApoA1 and ApoB100, have been quantified in the extracellular medium as a function of time, either by immunoblot or ELISA. In addition, the expression and inducibility of CYP proteins of the CYP1, CYP2 and CYP3 families in response to their prototypical inducers including 2,3,7,8-tetrachlorodibenzo(p)dioxin and rifampicin, have been evaluated by immunoblot analysis of microsomes or cell lysates. Moreover, the oxidative metabolism of cyclosporin A, a monoxygenase activity depending on CYP3A4, has been monitored directly on the cultured cells by HPLC analysis of extracellular medium. Our results show that, under these culture conditions, adult human hepatocytes retain these phenotypical characteristics for at least 35 days. This system meets the requirements for use as a model for screening CYP protein inducers.

Optical isomers of dihydropyridine calcium channel blockers display enantiospecific effects on the expression and enzyme activities of human xenobiotics-metabolizing cytochromes P450
2016, Toxicology Letters
Dihydropyridine calcium channel blockers (CCBs) are used as anti-hypertensives and in the treatment of angina pectoris. Structurally, CCBs have at least one chiral center in the molecule, thereby existing in two or more different enantiomers. In the current paper we examined effects of benidipine, felodipine and isradipine enantiomers on the expression and enzyme activities of human xenobiotics-metabolizing cytochromes P450.
All CCBs dose-dependently activated aryl hydrocarbon receptor (AhR) and pregnane X receptor (PXR), as revealed by gene reporter assays. Activation of AhR, but not PXR, was enantiospecific. Consistently, CCBs induced CYP1A1 and CYP1A2 mRNAs, but not protein, in human hepatocytes and HepG2 cells, with following pattern: benidipine (−) > (+), isradipine (−) > (+) and felodipine (+) > (−). All CCBs induced CYP2A6, CYP2B6 and CYP3A4 mRNA and protein in human hepatocytes, and there were not differences between the enantiomers. All CCBs transformed AhR in its DNA-binding form, as revealed by electromobility shift assay. Tested CCBs inhibited enzyme activities of CYP3A4 (benidipine (+) > (−); felodipine (−) > (+); isradipine (−)–(+)) and CYP2C9 (benidipine (−) > (+); felodipine (+) > (−); isradipine (−) > (+)). The data presented here might be of toxicological and clinical importance.
Human induced pluripotent stem cells in hepatology: Beyond the proof of concept
2014, American Journal of Pathology
The discovery of the wide plasticity of most cell types means that it is now possible to produce virtually any cell type in vitro. This concept, developed because of the possibility of reprogramming somatic cells toward induced pluripotent stem cells, provides the opportunity to produce specialized cells that harbor multiple phenotypical traits, thus integrating genetic interindividual variability. The field of hepatology has exploited this concept, and hepatocyte-like cells can now be differentiated from induced pluripotent stem cells. This review discusses the choice of somatic cells to be reprogrammed by emergent new and nonintegrative strategies, as well as the application of differentiated human induced pluripotent stem cells in hepatology, including liver development, disease modeling, host-pathogen interactions, and drug metabolism and toxicity. The actual consensus is that hepatocyte-like cells generated in vitro present an immature phenotype. Currently, developed strategies used to resolve this problem, such as overexpression of transcription factors, mimicking liver neonatal and postnatal modifications, and re-creating the three-dimensional hepatocyte environment in vitro and in vivo, are also discussed.
Hepatocyte function within a stacked double sandwich culture plate cylindrical bioreactor for bioartificial liver system

Small spheroids collide with one another to form larger spheroids, leading to poor oxygen and nutrient access; as well as decreased cell viabilities and functions in the spheroid center [19,20]. In contrast, the sandwich cultures are shown to maintain many liver-specific functions (e.g. albumin and urea productions, cytochrome P450 metabolic activities) [14,21], and have been utilized in several flat-bed bioreactors for BAL application [22–24]. However, limitations such as dead volume, regulation of shear stress level on cell surface, oxygen supply, and scalability of bioreactor, have not been adequately addressed in these designs [6].
Bioartificial liver (BAL) system is promising as an alternative treatment for liver failure. We have developed a bioreactor with stacked sandwich culture plates for the application of BAL. This bioreactor design addresses some of the persistent problems in flat-bed bioreactors through increasing cell packing capacity, eliminating dead flow, regulating shear stress, and facilitating the scalability of the bioreactor unit. The bioreactor contained a stack of twelve double-sandwich-culture plates, allowing 100 million hepatocytes to be housed in a single cylindrical bioreactor unit (7 cm of height and 5.5 cm of inner diameter). The serial flow perfusion through the bioreactor increased cell-fluid contact area for effective mass exchange. With the optimal perfusion flow rate, shear stress was minimized to achieve high and uniform cell viabilities across different plates in the bioreactor. Our results demonstrated that hepatocytes cultured in the bioreactor could re-establish cell polarity and maintain liver-specific functions (e.g. albumin and urea synthesis, phase I&II metabolism functions) for seven days. The single bioreactor unit can be readily scaled up to house adequate number of functional hepatocytes for BAL development.
The new murine hepatic 3A cell line responds to stress stimuli by activating an efficient Unfolded Protein Response (UPR)
2012, Toxicology in Vitro
Citation Excerpt :
The effort to establish a differentiated hepatic cell line able to express in vitro the most important liver functions (such as the synthesis of specific serum proteins, the metabolism of carbohydrates and lipids, and the modification and excretion of endogenous and exogenous molecules) has long been pursued in several laboratories and different model systems have been described to date (Ferrini et al., 1997; Gebhardt et al., 2003; Hewitt et al., 2007).
In the present study we have investigated the properties of a novel cell line (3A cells) obtained from the liver of 14.5 days post coitum (dpc) wild-type mouse embryo. 3A cells morphology was characterized by fluorescent localization of F-actin and β-catenin. The expression of specific genes and proteins essential to liver function in these cells was comparable or even more efficient then in the differentiated hepatocytic cell line MMH-D6. 3A cells also showed the capability to excrete molecules in extracellular spaces resembling functional bile canaliculi, glycogen storage activity and the ability to control retinol-binding protein 4 secretion in response to retinol deprivation. Their response to the exogenous stress stimulus induced by tunicamycin was analysed by PCR Pathway Array containing 84 genes involved in the Unfolded Protein Response (UPR). 3A cells were shown to activate the UPR following a typical stressful event, indicating that this cellular model could be further exploited to investigate hepatic proteins secretion and specific reaction to different injuries.
Comparative study of culture conditions for maintaining CYP3A4 and ATP-binding cassette transporters activity in primary cultured human hepatocytes
2011, Journal of Pharmacological Sciences
The aim of this study was to determine suitable culture conditions for maintaining the activity of cytochrome p450 (CYP) 3A4 and drug transporters in primary cultured human hepatocytes. Human hepatocytes were isolated using the two-step collagenase perfusion technique and were cultured with four different media, serum-free William’s E medium (serum-free WEM), WEM containing fetal calf serum (FCS-WEM), WEM with human serum (HS-WEM), and Lanford’s medium. The albumin levels were maintained for 7 days in hepatocytes. Although CYP3A4 mRNA levels gradually decreased from 3 days, CYP3A4 and hepatocyte nuclear factor-4α alpha protein levels and activities were maintained for 7 days in hepatocytes cultured with serum-free WEM and Lanford’s but not in those with FCS-WEM and HS-WEM. Furthermore, CYP3A4 protein levels were significantly increased by the addition of rifampicin and dexamethasone to the culture media, indicating that the induction potential was maintained. The protein levels of P-glycoprotein, multi-drug-resistance-2, and breast cancer-resistance protein were maintained for 7 days in all media. Serum-free WEM and Lanford’s also maintained protein levels of CYP2C19, CYP2D6, and organic anion transporter polypeptide in the hepatocytes. Serum-free WEM and Lanford’s may be appropriate culture media for maintaining CYP3A4 and drug transporter protein levels in primary cultured hepatocytes.
Effects of dinuclear copper(II) complexes with 6-(benzylamino)purine derivatives on AhR and PXR dependent expression of cytochromes P450 CYP1A2 and CYP3A4 genes in primary cultures of human hepatocytes
2010, Toxicology in Vitro
A series of dinuclear copper(II) complexes of the compositions [Cu₂(μ-L_n)₂(μ-Cl)₂Cl₂] (1, 2), [Cu₂(μ-L_n)₄Cl₂]Cl₂·2H₂O (3, 4) and [Cu₂(μ-L_n)₄(ClO₄)₂](ClO₄)₂·xSolv (5, 6; xSolv = 4MeOH for 5 and 2EtOH for 6), involving 6-(benzylamino)purine derivatives (L_n), have been evaluated with the aim to determine their possible drug interactions and their capability to induce the expression of major drug-metabolizing cytochromes P450. The above-mentioned complexes have been chosen based on the fact that substantial both in vitro (cytotoxicity, SOD-mimic) and in vivo (antidiabetic) biological activity has been found for them. As models, primary cultures of human hepatocytes and human hepatoma cells HepG2 transiently transfected with a plasmid containing dioxin-responsive element fused to the luciferase reporter gene (DRE-LUC) have been chosen. It has been found that the tested complexes 1–6 did not significantly induce the expression of CYP1A2 and CYP3A4 mRNAs in the concentration range of 0.1–10.0 μM, in three different primary human hepatocyte cultures after 24 h of the treatment. On the other hand, the model inducers, i.e. 2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD) and rifampicin, significantly increased the levels of CYP1A2 and CYP3A4 mRNAs in all cultures. In addition, compounds 1–6 did not transactivate DRE-LUC in transiently transfected HepG2, while TCDD strongly induced luciferase activity after 24 h of incubation. Based on the obtained results, it may be concluded that the studied dinuclear copper(II) complexes 1–6 possess very low toxicological potential to cause drug interactions in terms of transcriptional activation of the major human cytochromes P450.
