Intestinal explant barrier chip: long-term intestinal absorption screening in a novel microphysiological system using tissue explants

The majority of intestinal in vitro screening models use cell lines that do not reflect the complexity of the human intestinal tract and hence often fail to accurately predict intestinal drug absorption. Tissue explants have intact intestinal architecture and cell type diversity, but show short viability in static conditions. Here, we present a...

Advanced epithelial lung and gut barrier models demonstrate passage of microplastic particles

Micro- and nanoplastics (MNP) can be found virtually everywhere around us in the biosphere and food chain, therefore humans are continuously exposed to MNP, mainly via inhalation and ingestion. Here, we have applied physiologically relevant human-based advanced in vitro models representing the lung (MucilAir™) and gut (InTESTine™ and Intestinal...

Intestine-on-a-chip Next level in vitro research model of the human intestine

Over the past decade, microfluidic intestine-on-a-chip models have been emerging as a novel platform to study intestinal function in health and disease. These microphysiological systems surpass conventional in vitro intestinal model systems, as they add microenvironmental context in the form of mechanical cues or by the incorporation of multiple...

Evaluation of Normothermic Machine Perfusion of Porcine Livers as a Novel Preclinical Model to Predict Biliary Clearance and Transporter-mediated Drug-Drug Interactions using Statins

There is a lack of translational preclinical models that can predict hepatic handling of drugs. In this study we aimed to evaluate the applicability of normothermic machine perfusion (NMP) of porcine livers as a novel ex vivo model to predict hepatic clearance, biliary excretion and plasma exposure of drugs. For this evaluation we dosed...

The progress of intestinal epithelial models from cell lines to gut-on-chip

Over the past years, several preclinical in vitro and ex vivo models have been developed that helped to understand some of the critical aspects of intestinal functions in health and disease such as inflammatory bowel disease (IBD). However, the translation to the human in vivo situation remains problematic. The main reason for this is that these...

Towards human ex vivo organ perfusion models to elucidate drug pharmacokinetics in health and disease

To predict the absorption, distribution, metabolism and excretion (ADME) profile of candidate drugs a variety of preclinical models can be applied. The ADME and toxicological behavior of newly developed drugs are often investigated prior to assessment in humans, which is associated with long time-lines and high costs. Therefore, good predictions...
