TLDR
Using a co‐culture system, a plateau in which the state of differentiation was stabilized could be generated for co‐cultured hepatocytes isolated from adult rat and a disappearance of the initial expression of α1‐fetoprotein and the increase and/or maintenance of albumin secretion were measured.
Abstract
Sinusoidal cells isolated from adult rat liver have been established in primary culture and in cell line. The presence of factor VIII R:Ag and peroxidatic/phagocytosis activities were the criteria used to distinguish in freshly isolated cells the endothelial cells from the Kupffer cells and suggested the endothelial origin of the cell line. Using a co-culture system, the effect of sinusoidal liver cells on hepatocyte functional activity was characterized. A plateau in which the state of differentiation was stabilized could be generated for co-cultured hepatocytes isolated from adult rat and a disappearance of the initial expression of alpha 1-fetoprotein (AFP) and the increase and/or maintenance of albumin secretion were measured with co-cultured hepatocytes isolated from suckling rat. The presence of dexamethasone was required for such beneficial effect. The hepatocyte-stabilizing activity was also produced by a pulmonary endothelial cell line.

Recent advances in 2D and 3D in vitro systems using primary hepatocytes, alternative hepatocyte sources and non-parenchymal liver cells and their use in investigating mechanisms of hepatotoxicity, cell signaling and ADME.

Patricio Godoy, +94 more
TL;DR: This review encompasses the most important advances in liver functions and hepatotoxicity and analyzes which mechanisms can be studied in vitro and how closely hepatoma, stem cell and iPS cell–derived hepatocyte-like-cells resemble real hepatocytes.

Effect of cell–cell interactions in preservation of cellular phenotype: cocultivation of hepatocytes and nonparenchymal cells

TL;DR: Although the precise mechanisms by which nonparenchymal cells modulate the hepatocyte phenotype remain unelucidated, some new insights on the modes of cell signaling, the extent of cell–cell interaction, and the ratio of cell populations are noted.

Whole-Organ Tissue Engineering: Decellularization and Recellularization of Three-Dimensional Matrix Scaffolds

TL;DR: In this paper, the fundamental concepts of whole-organ engineering, including characterization of the extracellular matrix as a scaffold, methods for decellularization of vascular organs, potential cells to reseed such an acellular, naturally occurring three-dimensional biologic scaffold material that can then be seeded with selected cell populations.

Whole-Organ Tissue Engineering: Decellularization and Recellularization of Three-Dimensional

TL;DR: The fundamental concepts of whole-organ engineering, including characterization of the extracellular matrix as a scaffold, methods for decellularization of vascular organs, potential cells to reseed such a scaffolds, techniques for the recellularization process and important aspects regarding bioreactor design to support this approach are described.

Controlling cell interactions by micropatterning in co-cultures: hepatocytes and 3T3 fibroblasts.

TL;DR: This co-culture technique allowed manipulation of the initial cellular microenvironment without variation of cell number and was able to control the level of homotypic interaction in cultures of a single cell type and the degree of heterotypic contact in co-cultures over a wide range.

Preparation of rat liver cells: II. Effects of ions and chelators on tissue dispersion☆

TL;DR: Electrolysis of rat liver tissue by perfusion with collagenase and hyaluronidase was maximally stimulated by Ca2+ at 5 mM concentration, and enzymatic dispersion was optimal at pH 7.5.

Maintenance and reversibility of active albumin secretion by adult rat hepatocytes co-cultured with another liver epithelial cell type.

TL;DR: The results demonstrate for the first time long-term stabilization and reversibility of a specific function (albumin secretion) at high levels by adult hepatocytes cultured in serum-free medium and suggest that both the presence of other liver cell type(s) and the production of an extracellular matrix are needed for the maintenance of specific functions in cultured hepatocytes.

Hepatocyte proliferation in vitro: its dependence on the use of serum-free hormonally defined medium and substrata of extracellular matrix.

TL;DR: The culture conditions found to result in stable proliferation of normal rat hepatocytes are: subconfluent cell densities; serum-free medium; hormonally defined medium containing epidermal growth factor, insulin, glucagon, prolactin, and other growth factors; and substrata of liver extracellular matrix depleted of growth inhibitors.

TL;DR: It is concluded that supplementation of chemically defined medium with Me2SO enables maintenance of differentiated hepatocytes in culture for extended periods of time.

Phenotypic stability of adult rat hepatocytes in primary monolayer culture.

TL;DR: P phenotypic change occurs in primary hepatocyte culture, not only in mammalian but also in amphibian hepatocytes7; it is distinct from a process of senescence or impaired viability; and it may be quantitatively impressive, involving key hepatic functions.
