Two hypothermic preservation techniques were investigated to assess their possible role in on-demand cell supply for bioartificial liver support devices. Porcine hepatocytes from slaughterhouse organs were isolated and either cold stored in a modifie

Large numbers of lipophilic molecules are attached to fractions of serum protein, e.g. albumin, in vivo. Cell culture medium of most in vitro hepatocyte models for the prediction of metabolism does not contain albumin. Consequently, in vitro availabi

Objective: Hepatocytes are increasingly used as functional units in bioartificial liver devices. The objective of the present study was to investigate the feasibility of culturing porcine hepatocytes in high density on a novel polyurethane-based nonw

A new non-woven polyetherurethane support suitable to host cultured hepatocytes has been developed. Prior to its use in bioreactors and artificial liver devices, the biocompatibility of this new material was investigated. The experiments have shown t

For clinical use of bioartifical liver devices a constant supply of primary liver cells has to be provided. Hypothermic storage of isolated pig hepatocytes could support large-scale stocking of cells. Freshly isolated pig hepatocytes from slaughterho

Hepatocytes in long-term cultures represent a promising approach to preserve liver function under standard culture conditions. Hepatocyte cultures as the key components in an extracorporeal artificial liver (EAL) in the treatment of hepatic insuffici

It has been suggested that chenodeoxycholic acid is preferentially formed by the alternative or 'acidic' pathway of bile acid biosynthesis starting with 27-hydroxylation of cholesterol, while cholic acid is derived from 7 alpha-hydroxycholesterol whi

An easy to apply culture technique is presented that protects a monolayer configuration of liver cells within an extracellular matrix. The Immobilising Gel (IG)-Technique not only preserves hepatocyte morphology and supports a variety of differentiat

1. Primary cultures of human hepatocytes have already been employed in various applications for the study of xenobiotic metabolism. Most of these approaches were performed either on freshly isolated cells or on short-term primary cultures. Standard c

Self designed temperature probes with identical transmission patterns were placed at different positions within the cooling chamber of a modern cooling machine under defined conditions. Dependent on the rate of cooling, considerable differences betwe
