By the use of monolayer cultures as an in vitro system, the effects of drugs on CYP3A activity can be evaluated. It relies on the use of a luminogenic CYP3A substrate, namely luciferin-6′-pentafluorobenzylether (luciferin- PFBE). Upon biotransformation by CYP3A, luciferin-PFBE is converted into

Liver functionality can be monitored by the urea synthesis. In culture medium the measurement of urea synthesis relies on a chromogenic reagent that specifically forms a colored complex with urea. The concentration of this complex between urea, o-phthalaldehyde and N-(1-naphthyl) ethylenediamine can

Albumin secretion in the supernatant of in vitro cultures can be measured by an enzyme-linked immunosorbent assay. The assay is based upon a quantitative sandwich enzyme immunoassay technique and measures albumin in the culture medium of primary hepatocytes and/or hepatocyte like cells. Standards

This method provides a new and easy to standardize enzymatic isolation protocol to obtain human umbilical cord-derived mesenchymal stromal cells (hUC-MSCs). hUC-MSCs are obtained within 3 hours and the isolation method provides a minimal risk of bacterial contamination. The so-obtained hUC-MSCs were

Human umbilical cord-derived mesenchymal stromal cells (hUC-MSCs) express several key liver-specific transcription factors as well as hepatic progenitor markers. However, they still lack the hepatocyte nuclear factors 1-alpha (HNF1a) and 4-alpha (HNF4a), indispensable for their reprogramming towards

HepG2 is a human hepatoma derived cell line, which are epithelial in morphology. It was established from liver tissue of a 15-year-old Caucasian male with a well differentiated hepatocellular carcinoma. The HepG2 cell line is one of the most used human liver-based in vitro models. The cells secrete

Cryopreserved differentiated HepaRG cells (obtained from Biopredic International) are derived from a human hepatocellular carcinoma. These cells are an unique in vitro tool that provides reproducible results and exhibit many characteristics of primary human hepatocytes such as morphology, expression

In this method, we use rabbit monoclonal antibodies that are produced in vitro to identify xenografted human stem cell-derived hepatocytes in frozen murine liver slices. These recombinant antibodies were produced in vitro by cloning antibody genes for immune-specific heavy and light antibody chains

Rat liver epithelial cells (rLEC) can be isolated from 8-day old male Sprague-Dawley rats. Briefly, small fragments of neonatal rat livers are incubated for 15 minutes with 4-(2-hydroxyethyl)-1-piperazine-ethanesulfonic acid (HEPES) buffered trypsin solution [0.25% (v/v)] and washed twice with
