Title:	Anti-inflammatory, skin-regenerative, whitening, antioxidant, or wound-healing composition containing culture medium of ADSC-T cells in which T-antigen is introduced into adipose-derived stem cell as active ingredient
Abstract:	The present invention relates to an anti-inflammatory, skin-regenerative, whitening, antioxidant, or wound-healing composition containing a culture medium of adipose-derived stem cell-T (ADSC-T) cells as an active ingredient, in which T-antigen is introduced into an adipose-derived stem cell. The culture medium of ADSC-T cells, according to the present invention, has remarkable effects for treating or inhibiting inflammation by alleviating atopic dermatitis, which is an autoimmune disease, and inhibiting NF-.kappa.B activities through an increase of an I.kappa.b.alpha. expression. Additionally, the culture medium, according to the present invention, exhibits: excellent skin regenerative effects by having effects of enhancing skin collagen elasticity and reducing wounds, in a collagen culture; excellent skin whitening effects by inhibiting tyrosinase activities and melanin production; and excellent anti-oxidation effects by inhibiting DPPH radical activities. Furthermore, the present invention has remarkable wound-healing effects by enhancing cell mobility of fibroblast, and is thus useful for anti-inflammation, skin-regeneration, whitening, anti-oxidation, or healing wounds.

Application Number:	14/785,265
Patent Claims:	1. A method for treating an inflammatory disease in a subject in need thereof, comprising administering to the subject a culture medium of adipose-derived stem cell-T (ADSC-T) cells in which T-antigen is introduced into an adipose-derived stem cell as an active ingredient. 2. The method of claim 1, wherein the T-antigen is introduced through transfection. 3. The method of claim 1, wherein the T-antigen is derived from Simian virus40 (SV40). 4. The method of claim 1, wherein the culture medium of the ADSC-T cell is prepared by a method comprising: (a) culturing the adipose-derived stem cells, where the adipose-derived stem cells were isolated through a centrifuge after treating an enzyme, collagenase, to a suctioned adipose tissue; (b) preparing the ADSC-T cells expressing a T antigen of SV40 by transfecting a plasmid expression vector into the adipose-derived stem cell cultured in the above step (a); and (c) obtaining a culture medium by culturing the ADSC-T cells prepared in the above step (b). 5. The method of claim 4, wherein the transfection in the above step (b) is carried out by at least one method selected from the group consisting of calcium phosphate transfection, electroporation, microinjection and liposome injection. 6. The method of claim 1, wherein the inflammatory disease is selected from the group consisting of allergic disease, atopic dermatitis, nasitis, asthma, acute pain, chronic pain, paradentitis, gingivitis, inflammatory bowel disease, gout, myocardial infarction, arteriosclerosis, congestive heart failure, hypertension, angina pectoris, stomach ulcer, Alzheimer's disease, cerebral infarction, Down's syndrome, multiple sclerosis, obesity, diabetes, dementia, depression, schizophrenia, tuberculosis, sleep disorder, sepsis, a burn, and pancreatitis. 7. A method for improving skin-regeneration in a subject in need thereof, comprising administering to the subject a culture medium of ADSC-T cells in which T-antigen is introduced into an adipose-derived stem cell as an active ingredient. 8. A method for skin-whitening in a subject in need thereof, comprising administering to the subject a culture medium of ADSC-T cells in which T-antigen is introduced into an adipose-derived stem cell as an active ingredient. 9. A method of promoting antioxidant activity or suppressing skin aging in a subject in need thereof comprising administering to the subject a culture medium of ADSC-T cells in which T-antigen is introduced into an adipose-derived stem cell as an active ingredient. 10. A method for promoting wound-healing in a subject in need thereof, comprising administering to the subject a culture medium of ADSC-T cells in which T-antigen is introduced into an adipose-derived stem cell as an active ingredient.
