  • Patent number: 11339196
    Abstract: The present invention relates to a cell therapeutic agent comprising a stem cell expressing Lin28, a pharmaceutical composition comprising a stem cell expressing Lin28 for the prevention or treatment of a neurological disorder, a bone disorder, a muscular system disorder, an epithelium-related disorder or a blood-related disorder, and a method for treating a neurological disorder, a bone disorder, a muscular system disorder, an epithelium-related disorder or a blood-related disorder using the composition. A stem cell excellent in terms of differentiation potency to various tissue cells and renewal ability can be prepared by introducing Lin28, which regulates an embryonic development procedure, or a vector expressing Lin28 during stem cell culturing, and by culturing the cell.
    Type: Grant

  • Patent number: 11045498
    Abstract: The present invention relates to a non-viral minicircle vector expressing a SOX gene, a stem cell into which the vector is introduced, a pharmaceutical composition for preventing or treating a cartilage disease, including the stem cell, and a method for constructing the vector. The transformation of mesenchymal stem cells with MC/SOX-Trio or MC/SOX-Duo, which is a non-viral minicircle vector according to the present invention, can completely exclude the necessity of expensive growth factors that have been indispensably used in inducing the differentiation of mesenchymal stem cells into chondrocytes. Accordingly, the mesenchymal stem cells transformed therewith, when implanted in vivo, can differentiate into chondrocytes by themselves, and thus have an advantage capable of simplifying the existing complicated steps of culturing cells to induce differentiation and then transplanting the cells.
