    • PURPOSE: A medium for maintaining the stemness of human embryonic stem cells or dedifferentiation pluripotent stem cells is provided to enable long-term culture(sub-culture). CONSTITUTION: A medium for maintaining the stemness of human embryonic stem cells or dedifferentiation pluripotent stem cells contains: protein kinase C inhibitor as a stemness-maintaining agent; a histone deacetylase inhibitor; or bone morphogenic protein channel blocker in a basic medium. The bone morphogenic protein channel block is noggin, chordin, follistatin, and 6-(4-(2-piperidine-1-ylethoxy)phenyl)-3-pyridine-4-ylpyrazolo(1,5-a)pyrimidine. The basic medium is a xenopathogen-free medium. A method for culturing the human embryonic stem cells or dedifferentiation pluripotent stem cells comprises a step of culturing human embryonic stem cells or dedifferentiation pluripotent stem cells.

    • PURPOSE: A manufacturing method of dedifferentiation pluripotent stem cell using dedifferentiation - enhancer is provided to enhance safety and to be suitable for being used in clinic. CONSTITUTION: A manufacturing method of dedifferentiation pluripotent stem cell using dedifferentiation - enhancer comprises the following steps: cultivating human originated somatic cell to which a gene coding a dedifferentiation induction factor is introduced in a culture medium which includes protein kinase C inhibitor, dedifferentiation-enhancer of bone morphogenetic protein channel blocker or histone deacetylase inhibitor; and separating embryonic stem cell-like colonies from the culture materials. The concentration of the dedifferentiation - enhancer is in a range of 0.001-1000 micro M. The first step comprises the following steps: cultivating the human originated somatic cell in a culture medium which is obtained by adding the dedifferentiation-enhancer to a culture medium used for dedifferentiation induction factor coding gene introduction for 3-6 days; secondary cultivating the human originated somatic cell in the first culturing medium for 1.5-3 days under the existence of extracellular matrix protein; and tertiary cultivating the human originated somatic cell in the second culture medium for 15-30 days.
