  • Method for purifying mesenchymal stem cells to improve transplantation efficiency
    Patent number: 11613733
    Abstract: A method for purifying and enriching mesenchymal stem cells (MSCs) simply and efficiently. Separation of cells expressing CD73 protein on the surface from fresh tissue isolated from a living body allows purification and enrichment of MSCs easily and efficiently. MSCs may be selectively isolated with a single antibody before culturing to establish a culture system of mesenchymal stem cells that enhances the engraftment efficiency in the transplanted site.
    Type: Grant
    Filed: May 11, 2018
    Date of Patent: March 28, 2023
    Assignees: Medical & Biological Laboratories Co., Ltd., JSR Corporation
