Patent number: 11965180Abstract: 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.Type: GrantFiled: August 14, 2020Date of Patent: April 23, 2024Assignee: Chugai Seiyaku Kabushiki KaishaInventors: Tatsumi Yamazaki, Hisafumi Okabe, Shinta Kobayashi, Yu Jau Chen, Atsuhiko Kato, Masami Suzuki, Koichi Matsubara
