    摘要: An 18 kDa protein, denominated FDF-3, has been isolated from cultures of human fibroblasts and has been found to potentiate the growth- and differentiation-promoting activities of certain cytokines toward hematopoietic progenitor cells. The amino acid sequence of the FDF-3 protein, shown in SEQ ID NO: 14, corresponds to the sequence of a C-terminal domain of human fibronectin. The protein is useful in combination with IL-3, G-CSF, GM-CSF, or SCF (stem cell factor) in the expansion of hematopoietic cell populations in vitro or in therapeutic methods to promote recovery from leukopenia or myelosuppresion in vivo.

    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.
