  • Publication number: 20200353426
    Abstract: A method for manufacturing a composite semipermeable membrane is capable of forming, on a surface of a porous support in a highly reproducible manner, a separation layer that is extremely thin and that exhibits superior separability. It provides, on a surface of a porous support, a composite semipermeable membrane that has an organic/inorganic hybrid separation layer that is extremely thin and that exhibits superior separability. A method for manufacturing a composite semipermeable membrane includes forming, on a surface of a porous support, a separation layer containing a cross-linked condensate having a siloxane bond by bringing an organic solution that contains an organic silicon compound containing three or more reactive functional groups, each of which is at least one type selected from a hydrolyzable group and a hydroxyl group, into contact with water or an aqueous solution on the porous support, and by performing interfacial polycondensation of the organic silicon compound.

  • Publication number: 20200237828
    Abstract: Multilineage-differentiating stress enduring (Muse) cells are stage-specific embryonic antigen-3 (SSEA-3) positive cells that exist in mesenchymal stem cell (MSC) populations. Muse cells have the pluripotency to differentiate into all germ layers as embryonic stem cells. The purpose of the present study is to investigate the efficacy of Muse cell transplantation for repairing osteochondral defects. Muse cells were isolated from human bone marrow MSCs. As osteochondral defects, the patellar grooves of immunodeficient rats were injured. Next, cells were injected into the mice so that the animals were divided into the following 3 groups: a control group to which PBS was injected; a non-Muse group to which 5×104 SSEA-3 negative non-Muse cells were injected; and a Muse group to which 5×104 SSEA-3 positive Muse cells were injected.
