Medicine for treatment and/or prevention of ischemic diseases, method for improving angiogenesis-promoting activity of cells, or method for producing medicine
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.
1. A method for improving angiogenesis-promoting activity of blood cells or hemocytes, the method comprising: adding a copolymer of sucrose and epichlorohydrin to the blood cells or the hemocytes in a cell suspension; incubating the blood cells or the hemocytes with the copolymer of sucrose and epichlorohydrin for 5 minutes to 1 hour; and after incubating the blood cells and the hemocytes, separating the copolymer from the blood cells or the hemocytes using centrifugation.
2. The method of claim 1 , wherein if the blood cells or the hemocytes are bone marrow cells, an erythrocyte fraction is removed but a leukocyte fraction is not removed.
