Abstract: The present invention relates to a method for extracting collagen from a liposuction effluent, wherein collagen is extracted by treating a collagen-containing liposuction effluent in the presence of a supercritical fluid. According to the present invention, conventionally discarded collagen in a liposuction effluent can be extracted at high purity, and the extracted high purity collagen can be widely used in medical, pharmaceutical, and cosmetic products.

Abstract: The present invention provides: an extracellular matrix of which the biocompatibility is greatly increased through fat removal and decellularization and which contains growth factors so as to control physiological activities of cells; and a method for preparing the same. In addition, the extracellular matrix may be effectively obtained through a solvent extraction process using supercritical fluid, and a preservation solution comprising the extracellular matrix may be preserved for a long time by preventing contamination, and has increased manageability so that usability of the extracellular matrix may be greatly increased.
