ABSTRACT:
The present invention provides liver parenchymal cells having a clonal growth ability, which possesses at least one of the cell biological properties such as: presence of peroxysome; being positive to hepatocyte-markers; being partially positive to neoplastic hepatocyte-markers or immature hepatocyte-markers; being positive to antibodies against the surface antigens of ovall cells; and being partially positive to bile duct cell-markers. The present invention also provides a method for obtaining such cells and a method for subculturing such cells.
With the liver parenchymal cells above, it will be possible to research in detail the process of development and differentiation, the mechanisms of growth and functional expression of hepatic cells, and to open up a new way to clalification of mechanisms or hepatoma and various other diseases and to development of therapeutic method against these disseases.
