  • Patent number: 11965180
    Abstract: Provided is a cancer stem cell mass from which cells incapable of forming cancer are substantially removed and which has a characteristic property of reproducing a layered structure of a cancer tissue; a process for producing the cancer stem cell mass; and use of the cancer stem cell mass. A human cancer tissue was repeatedly grown in a NOG mouse, separated cancer cells from the grown cancer tissue, and tested and compared various cancer cell culture processes. As a result, a cancer stem cell composition which is homogeneous and is substantially free of the coexistence of cells capable of forming cancer and cells incapable of forming cancer in a mixed state can be produced successively by employing an attached culture process using a serum-free stem cell culture medium rather than a generally employed floating culture process.

  • Publication number: 20240052059
    Abstract: The present inventors examined the procoagulant activity of a multispecific antigen-binding molecule that functionally substitutes for FVIII using blood and plasma derived from FIX disorder patients. The result showed that multispecific antigen-binding molecules that functionally substitute for FVIII can be used not only as methods for preventing and/or treating bleeding in hemophilia A, acquired hemophilia A, von Willebrand disease, and hemophilia C, which are caused by FVIII dysfunction, but also as methods for preventing and/or treating bleeding in FIX disorders, because of their procoagulant activity. Furthermore, the effect of a FIX formulation could be enhanced by using it in combination with a multispecific antigen-binding molecule that functionally substitutes for FVIII, and it was shown that the combined use is promising as a combination therapy that shows stable hemostatic effects.
