  • Publication number: 20230406897
    Abstract: A method for isolating and culturing umbilical cord blood stem cells that express high levels of GDF-3 is disclosed. Umbilical cord blood stem cells isolated and cultured as described herein exhibit high expression of GDF-3. Stem cells with high expression of GDF-3 maintain high proliferation capacity contrary to conventional stem cells even as passages progress, allowing for the advantage of obtaining a large quantity of healthy stem cells. Furthermore, due to the higher proliferation rate of stem cells, it has been observed that the concentration of extracellular matrix components secreted by the cells is also higher. Therefore, when utilizing GDF-3 high-expressing umbilical cord blood stem cells for the production of cell and culture medium compositions, it is possible to produce raw materials with excellent efficacy and effects.

  • Publication number: 20230151331
    Abstract: The present invention relates to a method for preparing a culture medium containing exosomes released by umbilical cord blood stem cells. The preparation method is based on culturing the umbilical cord blood stem cells in a serum-free medium supplemented with GDF-11, EGF, FGF2, TFG-?1, and/or VEGF. The culture medium produced by treating umbilical cord blood stem cells with a serum-free medium supplemented with 5 types of growth factors and the exosomes isolated from the culture medium has a higher total protein content and extracellular matrix protein content, when compared to a culture medium produced by culturing umbilical cord blood stem cells in a serum-free medium to which the growth factor is not added. In addition, exosomes released by umbilical cord blood stem cells cultured in a serum-free medium containing five growth factors have a high concentration, a small size, and an even distribution.
