A method for enhancing an expression of insulin like growth factor 1 receptor in a mesenchymal stem cell is provided. The method includes culturing the mesenchymal stem cell expressing insulin-like growth factor 1 receptor in a medium containing platelet-derived growth factor BB (PDGF-BB) to enhance the expression of insulin like growth factor 1 receptor in the mesenchymal stem cell.

Provided are a composition and a sheet, including a mesenchymal stem cells-hydrogel-biodegradable support or a mesenchymal stem cells-hydrogel-nondegradable support and a preparing method thereof. More specifically, in the sheet including a mesenchymal stem cells-hydrogel-biodegradable support or a mesenchymal stem cells-hydrogel-nondegradable support according to the present invention, the high-active mesenchymal stem cells may be applied to a wounded part of a patient with epidermolysis bullosa as it is without isolation using proteases, and in the culturing, an extracellular matrix such as collagen, laminin, fibronectin, and elastin secreted from the mesenchymal stem cells is wholly present on the hydrogel to have an advantageous effect that skin reproduction and re-epithelization abilities are significantly excellent as compared with conventional dressing agents used for epidermolysis bullosa.

Methods for improved handling of isolated canine umbilical cord mesenchymal stromal cells (UC-MSCs), including methods for expansion of canine UC-MSCs, cryopreservation and improved post-thaw viability using adherent plates, as well as standardized methods and kits for characterizing isolated canine UC-MSCs in a cell population. Methods for improved detachment or dissociation of adherent cells and new dissociation reagents comprising nattokinase are also disclosed.

The purpose of the present invention is to provide a novel medical application of pluripotent stem cells (muse cells) in regeneration medicine. The present invention provides a cell preparation and a pharmaceutical composition which are for amelioration and treatment of brain disorders resulting from fetal growth retardation, such as abnormal motor quality or abnormal neurological development, and which contain SSEA-3 positive pluripotent stem cells isolated from a mesenchymal tissue from a live body or cultured mesenchymal cells. It is assumed that this cell preparation is based on a mechanism where muse cells that are administered to objects having the disorders are engrafted on an impaired brain tissue, thereby ameliorating or treating the disorders.

A method for enhancing an expression of insulin like growth factor 1 receptor in an umbilical cord mesenchymal stem cell is provided. The method includes culturing the umbilical cord mesenchymal stem cell expressing insulin-like growth factor 1 receptor in a medium containing platelet-derived growth factor BB (PDGF-BB) to enhance the expression of insulin like growth factor 1 receptor in the umbilical cord mesenchymal stem cell.

The invention discloses means of treating lung degenerative diseases including chronic obstructive pulmonary disease (CODP) using umbilical cord mesenchymal stem cells such as JadiCells alone, and/or using said cells under conditions that are activated in order to endow enhanced regenerative activity. In one embodiment said activation of said mesenchymal stem cells is performed through stimulation with a toll like receptor agonist at a concentration and duration sufficient to induce a >50% increase in keratinocyte growth factor expression from said stem cells. In another embodiment the invention provides the use of JadiCells as a means of producing exosomes, wherein said exosomes possess therapeutic properties capable of reducing inflammation, fibrosis and degeneration associated with COPD, as well as stimulation of regenerative activity. In some JadiCells are activated by a treatment with Activated Protein C.

The current invention relates to a cell composition comprising isolated mesenchymal stem cells, wherein said MSCs are radiolabeled with technetium-99m, wherein said radiolabel is essentially free of hexamethylpropylene amine oxime, and wherein said radiolabeled MSCs have a post-labeling cell viability of at least 55%. The invention also relates to the use of said cell composition for biodistribution, diagnostics and cell-based therapies. Furthermore, the invention relates to a method for preparing radiolabeled mesenchymal stem cells.

A method for purifying and enriching mesenchymal stem cells (MSCs) simply and efficiently. Separation of cells expressing CD73 protein on the surface from fresh tissue isolated from a living body allows purification and enrichment of MSCs easily and efficiently. MSCs may be selectively isolated with a single antibody before culturing to establish a culture system of mesenchymal stem cells that enhances the engraftment efficiency in the transplanted site.

The present invention relates to the field of cell therapy, and specifically relates to a method for producing a mesenchymal stem cell population, the mesenchymal stem cell population and a culture supernatant thereof produced by the method, and a pharmaceutical composition containing such cells or the culture supernatant thereof. The present invention further relates to use of the mesenchymal stem cell population and the culture supernatant thereof for preventing and treating diseases.

Provided is a method for treating diseases related to cardiac tissue damage or cardiac insufficiency in a subject. The method includes the step of locally applying a mesenchymal stem cell sheet such as an umbilical cord mesenchymal stem cell sheet to the heart of the subject. Also provided are related use and compositions of the mesenchymal stem cell sheet.
