Abstract:

We confirmed hepatocyte differentiation from embryonic stem (ES) cells in vitro. RT-PCR analysis revealed that a broad range of hepatic gene expression was observed in ES cells differentiated through formation of embryoid bodies (EBs) and its attachment culture. Quantitative PCR analysis revealed that hepatic gene expression related to early and late-stage liver development were enhanced through in vitro differentiation of ES cells. The presence of albumin-producing cells in the peripheral region of attached EBs was confirmed by immunocytochemical analysis. Future experiments will reveal the molecules that induce hepatocyte differentiation from ES cells in vitro. This research will provide systems for the investigation of mechanisms in liver development and establish a method of ES cell-based therapy for liver diseases.

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.
