  • Publication number: 20190374580
    Abstract: Provided is a method of preparing a three-dimensional cell spheroid, the method including forming the cell spheroid by co-culturing adipose-derived stem cells or mesenchymal stem cells with hepatocytes. According to the cell spheroid prepared by the method, the secretome secreted by the adipose-derived stem cells affects hepatocyte maturation, and therefore, hepatic functions of the finally formed three-dimensional cell spheroid, i.e., organoid, may be enhanced. Further, a composition including a culture medium of the adipose-derived stem cells may prevent or treat liver diseases including hepatitis, hepatotoxicity, cholestasis, fatty liver, etc., and may enhance hepatic functions.
