23 Jul Liver bud stem cell, preparation method and application thereof
Abstract
The invention relates to the technical field of biomedicine, in particular to a liver bud stem cell, a preparation method and the use thereof. The stem cell biology obtains the rapid development in the recent years. The isolation, the culture and the in-depth research of liver stem/progenitor cells have very important values for the occurrence mechanism of liver development, liver tumor and liver regeneration and the prevention and the treatment of various liver diseases. The currently and successfully cultured liver stem/progenitor cell systems are very limited. The invention is the multipotential stem cell which is isolated from a human embryonic liver bud tissue with the pregnancy of 4.5 to 6 weeks, thereby having significance for knowing the liver development, the regeneration and other related medical problems, providing an ideal cell model for the research of the liver stem cell biology and possibly providing an ideal cell source for the research of the cell therapy of liver diseases caused by various factors, the drug screening, the tissue engineering and other fields.
