Abstract: The present invention relates to a medical composition and a method for preparing the same, the medical composition comprising: an adipose tissue-derived extracellular matrix powder; and a biocompatible polymer or a crosslinked product of the biocompatible polymer. The medical composition according to the present invention exists in a well-aggregated state even after implantation in the body and can maintain the volume thereof for a certain time.

Abstract: The present invention relates to a decellularized nerve graft using allogeneic and heterologous nervous tissues and a method of manufacturing the same. In the present invention, by using a low-concentration basic solution and a surfactant as a decellularization solution, cell and tissue toxicity caused by a solvent or surfactant remaining in the tissue may be minimized by minimizing the use of a basic solution and an anionic surfactant in the entire manufacturing process. In addition, a peristaltic pump may be used to maintain the tissue structure and effectively remove lipid and cells.

Abstract: The present invention relates to an allogeneic and heterologous adipose tissue-derived extracellular matrix scaffold, and a method for producing the same. An adipose tissue-derived extracellular matrix scaffold according to the present invention has a composition similar to the human body, a large surface area, and an interconnected porous structure, and thus has high cell affinity and allows cells to survive for long periods.

Abstract: A zinc-alpha-2-glycoprotein (ZAG) protein-derived peptide according to the present invention shows an expression reducing effect of various immune factors shown in acute or chronic atopic dermatitis, and has a decreased immune response and decreased IgE expression and thus may be used to prevent, treat or improve xeroderma or an abnormal skin barrier function such as atopic dermatitis, an allergic disease or inflammation.

Abstract: An acellular dermal graft is provided. The acellular dermal graft may be useful in minimizing side effects caused after transplantation since an environment favorable for formation of new blood vessels and proliferation of autologous tissues is provided by forming a multi-penetration structure in an acellular dermal tissue, removing a basement membrane layer and/or subjecting corners to slope cutting, and transplantation is stably performed within a short transplantation time due to improved extensibility and flexibility of tissues. The acellular dermal graft may be useful in reducing a time required to recover tissues after transplantation since the transplantation is stably performed due to improved grafting reaction with a host tissue by enhancing uptake of fibroblasts and promoting angiogenic activities.
