| Research Abstract |
Expression of hepatic stem cell markers such as CD24, CD34, CD44, CD133, was examined in 7 cell lines derived from rat hepatocellular carcinomas. Although CD44 was commonly expressed in all the cell lines, it is also expressed in hepatic progenitor cells, small hepatocytes (SHs), which possess no ability to form tumors. To investigate the regulatory mechanism of the gene expression, the method of gene transduction to rat SHs by lentivirus infection was established. Knockdown of Follistatin in SHs by shRNA resulted in the growth inhibition.
