Abstract: A method for producing a cell culture containing desired cells is provided. The desired cells are induced to be differentiated from pluripotent stem cells. The method includes seeding a cell population by dispersing embryoid bodies obtained by inducing differentiation from the pluripotent stem cells to the desired cells. The embryoid bodies are dispersed at a density reaching confluence or higher.

Abstract: When detachment of a cell sheet from a culture dish has started at an unintended timing, immediately detach the cell sheet from the culture dish while preventing generation of wrinkles and the like in the cell sheet. A cell culture device captures an image of cells in the culture dish, and controls a cooling mechanism and a shaking mechanism based on the image so as to shake the cells while cooling them.

Abstract: The purpose of the present invention is to provide a therapeutic agent for dilated cardiomyopathy disease which produces excellent effects in the treatment of dilated cardiomyopathy (DCM) and provides a given benefit to a large number of patients. The present invention is a therapeutic agent for dilated cardiomyopathy comprising at least one selected from the group consisting of mesenchymal stem cell and microparticles derived from the mesenchymal stem cell. It is preferable that the mesenchymal stem cell is a cell having the ability to contain or secrete microparticles, that the microparticles have an average particle size of 1000 nm or less, and that they are exosomes.

Abstract: This composition can be easily added when cryopreserving cells and improves cell viability. 1 volume % of the composition containing 0.01 wt % to 20 wt % of a sophorose lipid is added just before or up to 6 hours before cryopreservation and cells are stored. This composition can improve cryopreservation cell viability as it reduces freezing damage to cells. With this composition, cells can be stored without using DMSO and blood serum. This is a simple and inexpensive storage method as it does not require fine control of the freezing rate during cell cryopreservation.

Abstract: The present invention addresses the problem of providing a disease-treating agent which exerts an excellent effect in treating diseases requiring an emergency surgery such as heart failure and which is efficacious at a certain level for a large number of patients. The present invention pertains to a kit for preparing a disease-treating agent, said kit comprising a) a fibrinogen solution, b) a thrombin solution and c) mesenchymal stem cells, in separate forms respectively. It is preferred that c) the mesenchymal stem cells are allogeneic to a subject to be treated. Also, the present invention pertains to a kit for preparing a disease-treating agent, said kit being to be used by, when in use, suspending c) the mesenchymal stem cells in either a) the fibrinogen solution or b) the thrombin solution, and then spraying the cell suspension thus obtained directly to a disease site substantially simultaneously with either b) the thrombin solution or a) the fibrinogen solution that is not used in the suspending step.

Abstract: The present inventors have found that HMGB1 fragment peptides having a particular amino acid sequence exhibit the effects of improvement of cardiac function, inhibition of cardiomyocyte hypertrophy, inhibition of myocardial fibrosis, and promotion of angiogenesis in an animal model of dilated cardiomyopathy, that the particular HMGB1 fragment peptides also exhibit the effects of improvement of cardiac function, inhibition of cardiomegaly, inhibition of cardiomyocyte hypertrophy, inhibition of myocardial fibrosis, and promotion of angiogenesis in an animal model of ischemic cardiomyopathy caused by old myocardial infarction, and that the particular HMGB1 fragment peptides exhibit the effects of inhibition of cardiomyocyte hypertrophy and inhibition of myocardial fibrosis in an animal model of hypertensive cardiomyopathy. Based on these findings, pharmaceutical compositions are provided for the prevention and/or treatment of cardiomyopathy and old myocardial infarction and chronic heart failure resulting therefrom, which comprise an HMGB1 fragment peptide having a particular amino acid sequence.
