  • Patent number: 10251916
    Abstract: An object of the present invention is to provide a cell composition for treatment of uterine tissue that heals damage occurring in uterine tissue, including intrauterine adhesion, to a state that enables pregnancy. In addition, an object of the present invention is to provide a method for producing this cell composition for treatment of uterine tissue, and a cell composition for treatment of uterine tissue produced according to that method. The cell composition, which has a first cell layer containing epithelial cells and a second cell layer containing stromal cells, and the first cell layer is laminated on the second cell layer, has the ability to heal damage occurring in uterine tissue, including intrauterine adhesion, and restore it to a state that enables pregnancy.

  • Patent number: 10172347
    Abstract: The present invention relates to a composition capable of improving storage stability of stem cells. More specifically, the present invention relates to a composition which contains a serum or a plasma for improving cold storage stability of stem cells. The composition for improving storage stability of stem cells according to the present invention can maintain a survival rate of over 90% for at least 9 days without changes in the properties, the number or the size of the stem cells, and thus is useful in the long-term transport of stem cells for cell therapy and the preparation of cell therapeutics injection products having an excellent effect.

  • Patent number: 10138292
    Abstract: The present disclosure related to isolated laminin-521, methods for making recombinant laminin-521, host cells that express recombinant laminin-521, and compositions containing laminin-521. Laminin-521 can maintain stem cells in vitro pluripotency, enable self-renewal, and enable single cell survival of human embryonic stem cells. When pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in the absence of differentiation inhibitors or feeder cells, the embryonic stem cells proliferate and maintain their pluripotency. It has also been discovered that human recombinant laminin-521 (laminin-11) provides single cell survival of stem cells after complete dissociation into a single cell suspension. Useful cell culture mediums containing at most 3.9 ng/ml of beta fibroblast growth factor (bFGF) are also described herein.
