Abstract:

It is difficult to a produce highly functional bioartificial liver (BAL) using only hepatocytes, because it is believed that liver-specific three-dimensional structure is necessary to maintain high function for BAL. But it is difficult to construct a culture system with liver-specific three-dimensional structure in vitro. To realize a highly functional culture system with liver-specific three-dimensional structure, we developed a culture system using liver slices that keep liver-specific architecture, such as liver lobule and hepatic microvascular system. Liver slices were embedded in agarose gel to maintain them under a moist and three-dimensional environment. We examined the viability and function of liver slices by using various shapes of agarose gel. Liver slices were cultured 1) under stationary condition (control), 2) directly embedded in gel, and 3) embedded in cylindrical gel for good drainage of medium and ventilation of air. The viability and function of the incubated liver slices were evaluated by LDH leakage, histomorphology, and immunohistochemistry. At 10 days, the morphological condition and function of liver slices embedded in cylindrical gel were maintained better than liver slices directly embedded in gel or in the stationary condition. We suggest that high functionality and morphological condition of liver slices could be maintained by embedding in cylindrical gel. In the future, it is possible that this method could be used to develop a highly functional bioartificial liver.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
