چکیده

Background Current in vitro and animal tests for drug development are failing to emulate the organ complexity of the human body and, therefore, to accurately predict drug toxicity. In this study, we present a self-contained, bioreactor based human in vitro tissue culture test system aiming to support predictive substance testing at relevant throughput. We designed a microcirculation system interconnecting several tissue culture spaces within a PDMS-embedded microfluidic channel circuit. The bioreactor is reproducibly perfused by a peristaltic on-chip micro-pump, providing a near physiologic fluid flow and volume to liquid ratio.

Assessment of troglitazone induced liver toxicity in a dynamically perfused two-organ Micro-Bioreactor system

Background The ever-growing amount of new substances released to the market and the limited predictability of current in vitro test systems has led to an ample need for new substance testing solutions. Many drugs like troglitazone, that had to be removed from the market due to drug induced liver injury, show their toxic potential only after chronic long term exposure. But for long-term multiple...

The Multi-organ Chip - A Microfluidic Platform for Long-term Multi-tissue Coculture

The ever growing amount of new substances released onto the market and the limited predictability of current in vitro test systems has led to a high need for new solutions for substance testing. Many drugs that have been removed from the market due to drug-induced liver injury released their toxic potential only after several doses of chronic testing in humans. However, a controlled microenviro...

A modular flow-chamber bioreactor concept as a tool for continuous 2D- and 3D-cell culture

Background Advanced cell culture models, especially long-term 3D systems, require bioreactors allowing for cultivation under continuous flow conditions. Such culture models are for example tissue engineered implants, 3D cultures for drug testing, in vitro models of cell growth and migration for wound healing studies, cell cultures for biomaterial testing. New challenges in drug testing and biom...

Laminar-flow immediate-overlay hepatocyte sandwich perfusion system for drug hepatotoxicity testing.

Drug hepatotoxicity testing requires in vitro hepatocyte culture to maintain the long-term and stable liver specific functions. We developed a drug testing platform based on laminar-flow immediate-overlay hepatocyte sandwich perfusion culture. The immediate-overlay sandwich (collagen-coated porous polymeric membrane as top overlay) protects the cells and integrity of the top collagen matrix fro...

In vitro liver model using microfabricated scaffolds in a modular bioreactor.

Hepatocyte function on 3-D microfabricated polymer scaffolds realised with the pressure-activated microsyringe was tested under static and dynamic conditions. The dynamic cell culture was obtained using the multicompartment modular bioreactor system. Hepatocyte cell density, glucose consumption, and albumin secretion rate were measured daily over a week. Cells seeded on scaffolds showed an incr...
