Abstract: 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.

Abstract: The present invention relates to a composition containing injectable mesenchymal stem cell-hydrogel and a method of preparing the same. Specifically, in a mesenchymal stem cell-hydrogel composition for injection prepared by a method of the present invention, since stem cells are attached to scaffolds in hydrogel beads, the stem cells are not easily lost or killed after the injection, and thus there is an advantage that an engraftment rate increases since the paracrine effect of the stem cells is continuously exhibited, and the stem cells are gradually released as hydrogel is degraded. In addition, the present invention has an advantage that healthy cells can be used without damages in cell membranes since injection formulation can be prepared without a treatment with proteolytic enzymes, and also a cryopreservation solution is easily removed from the mesenchymal stem cell-hydrogel beads even after freezing and thawing.
