Abstract

Tissue-specific stem cells from differentiating embryonic stem (ES) cells are both pluripotent and genetically flexible. Recent observations indicate that ES cells can differentiate into hepatocytes. Therefore, cell-based therapy can potentially be a therapeutic alternative to liver transplantation. In this study the treatment of acute liver failure in rats by transplantation of hepatocyte nuclear factor 4 (HNF4)-overexpressing ES cells was investigated. The HNF4 was transfected into ES cells and ES cell clones overexpressing HNF4 were selected. The levels of markers of hepatocyte differentiation, including albumin, transthyretin, glucose-6-phosphates (G-6-P) and SAPK/ERK kinase-1 (SEK1) mRNA, were tested in spontaneously differentiated HNF4-overexpressing ES cells by reverse transcription-polymerase chain reaction (RT-PCR). The ultrastructure of the spontaneously differentiated HNF4-overexpressing ES cells was examined by electron microscopy. To induce acute liver failure, Sprague-Dawley rats were subjected to 90% hepatectomy and given 5% oral dextrose. The rats were divided into three groups. The rats in the treatment group (n = 12) received intraliver injection of 2 x 10(7) undifferentiated HNF4-overexpressing ES cells from ...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.
