Method for inducing adult liver stem cells for transforming to high metastatic liver cancer cells and corresponding cells

The invention provides a method for inducing adult liver stem cells for transforming to high metastatic liver cancer cells and the stable liver cancer cells screened by the method. The method comprises the following steps: S1: performing amplification, culture and preservation of mice adult liver stem cells; S2: employing a gene transfection technology for transferring a lentiviral vector containing the Notch1 gene into the mice adult liver stem cells to obtain the mice adult liver stem cells for stable over-expression of the Notch1; S3: using the mice adult liver stem cells for stable over-expression of Notch1, employing a selective condition culture method for culture, performing in-vitro further differentiation, screening the liver cancer cells having strong and stable tumorigenic capability; and S4: employing the screened liver cancer cells, through an in-situ liver transplantation tumor model having same species, liver cancer is formed on liver, double-lung metastasis tumor is spontaneously formed, so th
