This method describes a well-known optimised human in vitro model of drug-induced cholestasis. Cryopreserved primary human hepatocytes are cultured between two layers of extracellular matrix scaffold, which will delay dedifferentiation and allows to restore cell-extracellular matrix interactions.

The method detects two facets of drug-induced cytotoxicity i.e. the intracellular accumulation of phospholipids and of neutral lipids, i.e. phospholipidosis and steatosis respectively. The assay makes use of a kit containing an aqueous, red-fluorescent formulation of labelled phospholipids (LipidTOX

This method assesses general cytotoxicity. Upon disruption of the cell membrane, lactate dehydrogenase (LDH) is released. LDH catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of reduced (NADH) and oxidized (NAD+) nicotinamide adenine dinucleotide. The principle

Thoracic aortic aneurysm (TAA) involves the progressive enlargement of the thoracic aorta, posing a significant risk for life-threatening aortic dissection and/or rupture. Currently, mouse models are frequently used to investigate and target the molecular defects underlying TAA, due to the

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

The present standard procedure describes a protocol for measuring the urea concentration in supernatant of human stem cell-derived hepatocyte-like cells. This procedure relies on a chromogenic reagent that forms a colored complex specifically with urea. The latter can be measured and is directly

The effect of fluidics that mimic the blood flow in the liver sinusoids, is evaluated during the hepatic differentiation of human skin-derived precursors (hSKP). In a standard bi-dimensional (2D) cell culture system, hSKP are differentiated to hSKP-HPC for 24 days in static conditions. In a
