PRIMITIVE AND PROXIMAL STEM HEPATOCYTES Russian patent published in 2008 - IPC A61K35/407 A61K35/48 C12N5/08 A61P1/16 

FIELD: medicine.

SUBSTANCE: group of inventions refers to human stem hepatocytes. Offered composition includes primitive human stem hepatocytes expressing Ep-CAM, AC 133 and albumin, and culture medium. These primitive human stem hepatocytes are precursors of proximal stem hepatocytes that are precursors of hepatocytes or precursors of bile ducts. Offered method of human cells liver-tissue precursors release includes identification of cells expressing Ep-CAM, AC 133 and albumin. Offered method of human hepatocytes precursors released by method under cl.15 or 16, cells precursors are primitive human stem hepatocytes expressing Ep-CAM, AC 133 and albumin. Offered method of human liver-tissue hepatocytes precursors release includes identification of cells expressing Ep-CAM. Offered method implies primitive human stem hepatocytes release expressing Ep-CAM, AC 133 and albumin. Offered primitive human stem hepatocytes expressing Ep-CAM, AC 133 and albumin released by method under cl. 26. Offered method implies proximal human stem hepatocytes release. Offered method provides treatment of liver dysfunction and diseases including introduction of primitive human stem hepatocytes in effective amount. Released primitive human stem hepatocytes are offered.

EFFECT: invention enables to apply produced compositions for cell therapy and bioartificial organs.
