Abstract: The present invention provides a sufficiently effective medicine for treatment and/or prevention of ischemic diseases, without performing isolation of therapeutic cells or removal of deleterious cells from blood cells/hemocytes. The blood cells and/or the hemocytes are subjected to the action of a saccharide. The saccharide is a monosaccharide, a disaccharide, a trisaccharide, a polysaccharides, or a copolymer containing a monosaccharide, a disaccharide, or a trisaccharide as a component. The saccharide is a copolymer of sucrose and epichlorohydrin.

Abstract: An object of the present invention is to provide a method for producing a mesenchymal stromal cell composition, comprising conveniently and aseptically separating high-purity amnion-derived MSCs by performing enzyme treatment only once. According to the present invention, the following are provided: a method for producing a mesenchymal stromal cell composition, comprising: performing enzyme treatment of an amnion with collagenase and thermolysin and/or dispase; and filtering the enzyme-treated amnion through a mesh; a method for producing a cryopreserved mesenchymal stromal cell composition; and a therapeutic agent comprising as an active ingredient the mesenchymal stromal cell composition for a disease selected from graft-versus-host disease, inflammatory bowel disease, systemic lupus erythematosus, liver cirrhosis, or radiation enteritis.

Abstract: Provided is a method for producing an economical bovine serum composition containing many factors useful for cell proliferation. The method includes a step of performing an anticoagulation treatment of bovine whole blood with an anticoagulant, a step of obtaining a buffy coat and a fraction with a heavier specific gravity than that of the buffy coat from the anticoagulated whole blood, and a step of promoting and activating an interaction between the obtained leukocytes and platelets at a given temperature for not less than a given time to cause secretion or release of a humoral factor from the leukocytes and/or platelets and performing a recoagulation treatment of blood components including the humoral factor with a re-coagulating agent.

Abstract: The object of the present invention is to provide a method for producing a cell population comprising mesenchymal stem cells having a high specific growth rate which are useful for promptly producing large amounts of cell formulations. The present invention provides a method for producing a cell population comprising mesenchymal stem cells, comprising: a step of treating a cell population comprising mesenchymal stem cells having different proliferative ability by physical stimulation or chemical stimulation, so as to select mesenchymal stem cells having relatively high proliferative ability, wherein the selected mesenchymal stem cells having relatively high proliferative ability are negative for CD106, and the expression level of a metallothionein family gene is increased in comparison to the expression level thereof in the cell population before the treatment by the physical stimulation or chemical stimulation.
