  • Patent number: 11666604
    Abstract: Disclosed are a multilayered cell sheet of cardiac stem cells (CSCs) and a method of manufacturing the same. In particular, the present disclosure provides a method of manufacturing a multilayered cell sheet according to a single step culture procedure by using, as a three-dimensional matrix, a biodegradable natural polymer hydrogel and embedding CSCs in the hydrogel. The multilayered cell sheet of the present disclosure does not require any special device for the manufacturing, is manageable with good physicomechanical property, increases a cell engraftment rate after transplantation based on sufficient accumulation of various growth and protective factors and extracellular matrix between cells, and is also self-assembled by the cell-mediated hydrogel compaction, making nutrients transfer easy. Therefore, the multilayered cell sheet of the CSCs is expected to be usefully applicable as a therapeutic agent for myocardium regeneration.

  • Publication number: 20210154373
    Abstract: The present disclosure relates to a method for immobilizing heparin and a NO-generating catalyst and a cardiovascular device having a surface modified using the same, and more particularly, to a method of co-immobilizing a heparin-phenol derivative and copper nanoparticles as a NO-generating catalyst on the surface of a material by a polyphenol oxidase-mediated reaction, a material having a surface with heparin and a NO-generating catalyst co-immobilized thereon by using the method, and a cardiovascular device including the material. It has been confirmed that a surface having heparin and the NO-generating catalyst co-immobilized thereon by the method of the present disclosure has high in vivo stability, continuously generates NO, and also promotes the proliferation of endothelial cells while significantly inhibiting the adhesion and activation of platelets and smooth muscle cells. Thus, the method may be advantageously applied to cardiovascular devices for inhibiting thrombosis and restenosis.

  • Patent number: 10888621
    Abstract: Provided are an injectable tissue adhesive hydrogel including gamma-cyclodextrin (?-CD). When such an injectable tissue adhesive hydrogel including the ?-CD is used as a skin glue, based on a fact that the ?-CD has a bigger hydrophobic cavity than that of ?- and ?-CDs, the injectable tissue adhesive hydrogel including the ?-CD has stronger interactions than host-guest interactions. In addition, hydrogen bonding in the injectable tissue adhesive hydrogel including the ?-CD can improve both cohesiveness and adhesiveness of gelatin. The injectable tissue adhesive hydrogel including the ?-CD having excellent cell viability is used for adhesion of a skin incision, to thereby effectively promote tissue regeneration.

  • Patent number: 9844610
    Abstract: The present invention relates to a method for preparing a hydrogel, including the steps of: preparing an enzyme-immobilized support; making contacting with a polymer having a phenol or aniline functional group at a side change and the support in the presence of hydrogen peroxide to cross-link the same; and obtaining a hydrogel by separating the enzyme-immobilized support. According to the present invention, a hydrogel is formed by cross-linking a polymer having a phenol or aniline functional group at a side chain through an enzyme-immobilized support, and thus a hydrogel containing no enzymes is obtained. Therefore, the biomedical application range of a hydrogel can be expanded since it is possible to overcome an in vivo safety problem such as immune reaction caused by an enzyme.
