Abstract: The present invention relates to a method for constructing a human pluripotent stem cell-derived liver organoid having enhanced drug metabolic potentials and a liver organoid constructed by the method. Because differentiation is made from human induced pluripotent stem cells dedifferentiated from somatic cells of patients, the cells are easily supplied so that patient-specific liver organoids can be prepared. The organoids can similarly simulate the real human liver structure because they consist of hepatocytes, cholangiocytes, gallbladder cells, and microduct structures, have excellent expression and functions of drug metabolism enzymes, and exhibit drug toxicity, drug metabolic capability, and drug-induced cardiotoxicity. Thus, the organoids can be advantageously used as liver models for searching for pathogenesis of liver diseases and for evaluating drug stability.
