Supernatant of brown adipocytes, method for preparing same and utilization thereof

Abstract

The present invention provides a composition having a metabolism-improving action, which comprises a supernatant of brown adipocytes or a purified product thereof. The present invention also provides a method of preparing the supernatant without using a culture solution comprising a high concentration of glucose. The present invention also provides a method of producing brown adipocytes using pluripotent stem cells, which are useful for preparing the supernatant of brown adipocytes. The present invention has succeeded in obtaining a supernatant having a metabolism-improving action from brown adipocytes. It was also possible to obtain the supernatant without using a culture solution comprising a high concentration of glucose. The present invention has also succeeded in producing brown adipocytes from pluripotent stem cells using a feeder-free culture system without adding a cytokine cocktail or the like. The brown adipocyte supernatant of the present invention is expected to be applied to the development of therapeutic agents and cosmetic products for glucose metabolism diseases.
