Figure 1 Culture of liver organoids in vitro. A: Liver organoids cultured from pluripotent stem cells (PSCs). Somatic cells are reprogrammed into induced PSCs; epidermal growth factor (EGF), fibroblast growth factor 2 (FGF2), and other substances are added to the medium; and the cells are cultured on Matrigel to form liver organoids; B: Liver organoids cultured from adult stem cells. Lgr5+ cells are isolated by fluorescence-activated cell sorting, and Wnt3a, Y27632, EGF, Rspo1, FGF, and other substances are added to form organoids by 3D culture. FACS: Fluorescence-activated cell sorting; iPSCs: Induced pluripotent stem cells; FGF2: Fibroblast growth factor 2; EGF: Epidermal growth factor.
