    摘要: The present invention relates to a method for producing human mast cells from human pluripotent stem cells. More particularly, the present invention provides a method for producing human mast cells from human pluripotent stem cells, comprising the steps of: (a) culturing human pluripotent stem cells under a condition suitable for promoting differentiation of the human pluripotent stem cells into hematopoietic progenitor cells expressing CD34; and (b) culturing the cells obtained in step (a) in the presence of hematopoietic factors comprising thrombopoietin (TPO) and Flt3 ligand.

    摘要: A hemopoietic stem cell augmenting agent in which at least one type of hepatocyte growth factor is contained as an active component is provided. The hepatocyte growth factor has an augmenting activity on undifferentiated pluripotent hemopoietic stem cells and is useful as a hemopoietic stem cell augmenting agent for treatment of bone marrow suppression and for treatment of bone marrow malfunctions and furthermore is useful for in vitro growth of peripheral blood stem cells and bone marrow stem cells. Furthermore, a hepatocyte growth factor derived from human normal fibroblasts which is considered to be a type of hepatocyte growth factor can be obtained by genetic recombination techniques, and said factor is also useful as a hemopoietic stem cells augmenting agent.
