摘要:
The present invention relates to a method for producing human eosinophils from human pluripotent stem cells. More specifically, the present invention provides a method for producing human eosinophils from human pluripotent stem cells, which method comprises the steps of: (1) co-culturing, in the presence of VEGF, human pluripotent stem cells with cells separated from the AGM region of a mammalian fetus; (2) performing suspension culture using a medium comprising IL-3, IL-6, Flt3 ligand, SCF, TPO and serum; (3) performing suspension culture using a medium comprising IL-3, SCF, GM-CSF and serum; and, optionally, (4) performing suspension culture using a medium comprising IL-3, IL-5 and serum.

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.

The present invention provides a method for screening drugs for suppressing inflammasome activity, using macrophages derived from induced pluripotent stem cells (iPS cells) having mutant NLRP3 gene.
摘要:
A dendritic cell is produced from pluripotent stem cells by culturing pluripotent stem cells by the following steps: (1) performing adherent culture in a medium which comprises a BMP family protein but does not comprise serum; (2) performing adherent culture in a medium which comprises VEGF but does not comprise serum; (3) performing adherent culture in a medium which comprises a hematopoietic factor but does not comprise serum; and (4) performing suspension culture in a medium which does not comprise serum.
摘要:
A blood analysis apparatus includes an analysis section. The analysis section is configured to compare a measurement spectrum obtained regarding red blood cells with a standard spectrum of heme, biliverdin, and bilirubin, and cause the measurement spectrum to belong to any one of the standard spectra.
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 provides useful means in an expansion culture system for a hematopoietic cell (hematopoietic stem cell, hematopoietic progenitor cell). Specifically, the present invention provides a composition for expanding a hematopoietic cell (hematopoietic stem cell, hematopoietic progenitor cell) containing recombinant human serum albumin; a serum-free medium for expanding a hematopoietic cell containing a basal medium and recombinant human serum albumin; a method of expanding a hematopoietic cell comprising culturing a hematopoietic cell in a serum-free medium containing recombinant human serum albumin, and a culture of a hematopoietic cell that can be obtained by the expansion method.
