  • Publication number: 20250099653
    Abstract: An embodiment relates to a phenol-modified decellularized muscle tissue-derived extracellular matrix (MEM) for muscle regeneration and a method for preparing same. The phenol group-modified decellularized MEM of the embodiment is characterized by containing components similar to original proteins of muscle tissue for muscle regeneration and forming a hydrogel having a stable porous nanofiber structure through dimerization crosslinking between phenol groups, wherein the hydrogel can effectively treat muscle injury or muscle diseases by being administered or implanted into muscle tissue without causing side effects such as an immune response or liver or kidney dysfunction.

  • Publication number: 20240026039
    Abstract: The provided is a hydrogel that utilizes the naturally occurring substance pectin to exhibit an equivalent or greater effect. Specifically, the present application is intended to provide a hydrogel or a patch which is stable, has strong adhesive strength, is advantageous for drug delivery, can be used for sustained treatment, has extremely low cytotoxicity, and is unlikely to induce an immune response, and thus can be used on various body parts, in particular the oral cavity. In addition, the provide is a hydrogel patch which employs a freeze-drying method prior to crosslinking, and thus exhibits superior adhesion to patches employing a post-crosslinking freeze-drying method.
