Abstract: The present disclosure relates to a composition for preventing, treating, or alleviating graft-versus-host disease, containing monoclonal stem cells obtained by subfractionation culture of stem cells, and to a graft-versus-host disease treatment method using the same. According to a method of subfractionation culture and proliferation of stem cells of the present disclosure, it is possible to obtain a large quantity of desired monoclonal stem cells in a short time by rapid proliferation of monoclonal stem cells, and the monoclonal stem cells obtained thereby are stem cells with enhanced therapeutic effects on graft-versus-host disease, and thus can be beneficially used as a graft-versus-host disease therapeutic agent.

Abstract: Disclosed is a composition for prevention, treatment or ameliorating of atopic dermatitis, the composition containing a monoclonal stem cell obtained via improved subfractionation culturing of a stem cell, a preparation method thereof, and a method for treating atopic dermatitis using the same. According to the improved subfractionation culturing and proliferation method of the stem cell, a desired amount of the monoclonal stem cells may be obtained in a massive manner in a short time via the rapid proliferation of the monoclonal stem cell. The monoclonal mesenchymal stem cell as obtained has an enhanced effect of treatment, prevention or ameliorating of atopic dermatitis, and thus may be usefully used for an atopic dermatitis treatment agent.

Abstract: The present invention relates to: a method for preparing a stem cell culture solution which contains growth factors and cytokines and is obtained by culturing, in a serum-free medium, mesenchymal stem cells cultured in a medium containing human platelet lysates (hPLs); and a cosmetic composition using the stem cell culture solution. When the method for preparing a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an hPL-containing medium is used, it is possible to obtain a mesenchymal stem cell culture solution which has a higher amount of cytokines and growth factors than that of a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an FBS-containing medium, and has excellent efficacy in the promotion of human dermal fibroblast proliferation, collagen synthesis, elastin synthesis, inhibition of melanin synthesis, and hair growth.

Abstract: Provided are a method and a composition for preventing or treating atopic dermatitis through administration of monoclonal stem cells and a method for screening atopic dermatitis patients suitable for administration of monoclonal stem cells and predicting prognosis of patients. According to the method for the subfractionation culture and proliferation of stem cells of the disclosure, large quantities of desired monoclonal mesenchymal stem cells can be obtained in a short period of time through rapid proliferation of monoclonal mesenchymal stem cells. In addition, the monoclonal mesenchymal stem cells thus obtained can be administered to atopic dermatitis patients according to a prescribed administration cycle, guidelines, and dose to effectively ameliorate atopy symptoms in the patients.

Abstract: The present disclosure relates to a composition for preventing, treating, or alleviating pancreatitis, containing monoclonal stem cells obtained by improved subfractionation culturing of stem cells, and to a method for preparing the same. According to the improved method of subfractionation culture and proliferation of stem cells of the present disclosure, it is possible to obtain a large quantity of desired monoclonal stem cells in a short time by rapid proliferation of monoclonal stem cells, and the monoclonal mesenchymal stem cells obtained thereby are stem cells with enhanced therapeutic effects on pancreatitis, and thus can may beneficially used as a pancreatitis therapeutic agent.

Abstract: The present disclosure relates to a subfractionation culturing method of a stem cell and proliferation method of a monoclonal stem cell obtained using the same. According to the subfractionation culturing method of stem cells and the proliferation thereof of the exemplary embodiments of the present disclosure, it is advantage that monoclonal stem cells may be quickly obtained without contamination, and desired monoclonal stem cells may be largely obtained in a short time through the rapid proliferation, thereby being used for the preparation of stem cell-therapeutic agents.

Abstract: The present invention relates to a composition and a method for inducing CD4+ T cells to differentiate into regulatory T cells and proliferate through an induced T cell co-stimulator ligand (ICOSL) or an ICOSL-overexpressing mesenchymal stem cell and for preventing or treating regulatory T cell-mediated diseases. The induced T cell co-stimulator ligand (ICOSL) or ICOSL-overexpressing mesenchymal stem cell according to the present invention effectively suppresses the proliferation of PBMCs, induces the expression of an ICOS in regulatory T cells, thereby inducing the differentiation and proliferation of the regulatory T cells through a PI3K-Akt mechanism, and thus can effectively prevent, treat, or enhance regulatory T cell-mediated diseases.

Abstract: Provided is a composition for preventing, treating or improving hair loss and promoting hair generation and hair growth, comprising a CXCL1 protein as an active ingredient. Further, provided is a composition for preventing, treating or improving hair loss and promoting hair generation and hair growth, comprising a CXCL1 protein and minoxidil as an active ingredient. The CXCL1 protein according to the present disclosure has no side effects at the time of treating hair loss and an excellent hair generation effect even in a short time and thus can be used as pharmaceutical products and usefully used as quasi-drugs, cosmetics and health functional foods.
