  • Artificial liver device
    Patent number: 5866420
    Abstract: Continuous cultures of pluripotent parenchymal hepatocytes were derived from the epiblasts of pig blastocysts. The cultures are feeder-dependent and grow slowly with doubling times of 3 to 4 days. They differentiate into large secretory duct-like structures or form small canaliculi. In combination with feeder cells and, optionally, adult pig hepatocytes and macrophages, the cells are useful in an artificial liver device which may be utilized as temporary liver support for the mitigation of the pathological effects of liver failure.
