  • Publication number: 20220340867
    Abstract: The present invention relates to a method for fabrication of an extracellular matrix-induced self-assembly and to fabrication of an artificial tissue using same. The method for fabrication of an extracellular matrix-induced self-assembly comprise the steps of: (a) decellularizing and powdering a tissue-derived extracellular matrix (ECM); and (b) adding the decellularized extracellular matrix powder to cells and culturing the cells to form a cell-extracellular matrix powder self-assembly. Accordingly, the self-assembly has characteristics similar to those of extracellular matrix tissues and can be fabricated into three-dimensional artificial tissues 1 cm or greater in size, thus finding advantageous applications as a cell therapy product and an artificial tissue implant.

  • Publication number: 20190070336
    Abstract: The present invention relates to a method for preparing a biocompatible porcine cartilage-derived extracellular matrix membrane capable of adjusting an in-vovo degradation rate and a mechanical property, and a composition containing the porcine cartilage-derived extracellular matrix as an active ingredient, for preventing adhesion between tissues and/or organs. Despite its high biocompatibility as a natural material, cartilage tissue extracellular matrix has a short decomposition period and its mechanical property is weak, thereby restricting the application. Accordingly, a method of enhancing the mechanical property through physical or chemical treatment and radiation treatment has been developed. In the present invention, biomaterials of various formulations were produced by treating the porcine cartilage-derived extracellular matrix with physiochemical methods.
