  • Patent number: 11949952
    Abstract: A television receiver 101 is connected to two or more wireless terminals via a communication line. A controller 214 and a network I/F 212 in the television receiver 101 send pieces of login information entered from the two or more wireless terminals to the content distribution server and obtain pieces of content list information each generated by the content distribution server based on the pieces of login information. An aggregated content list in which the obtained pieces of content list information are aggregated is generated. The display 210 displays the aggregated content list. The content list information includes content available for viewing on the information terminal connected to the communication line. The aggregated content list includes content available for viewing on the two or more information terminals in which the pieces of content list information are aggregated.

  • Patent number: 11858987
    Abstract: An objective of the present invention is to obtain two types of substantively homogeneous cancer stem cell populations which can be characterized using the cell surface marker Lgr5, and to provide cancer therapeutics using an antibody against a cell membrane molecule specifically expressed in these cancer stem cells by identifying said cell membrane molecule. A further objective is to provide, using an antibody against a cell membrane molecule specifically expressed in cancer stem cells, a reagent for detecting cancer stem cells, and a method for diagnosing and sorting cancer patients. The present inventors discovered that highly pure large intestine cancer stem cells (CSC) can be obtained in a large quantity, and identified the two types of conditions of large intestine CSCs distinguishable through Lgr5 expression. Moreover, the present inventors discovered that an antibody against a cell membrane molecule specifically expressed in said cancer stem cells can damage said cells.

  • Publication number: 20230085803
    Abstract: An objective of the present invention is to provide non-human animal models of cancer pathology, which mimic the hierarchical organization, cancer progression process, or biological property of human cancer tissues, and uses thereof. To achieve the objective described above, first, the present inventors transplanted cells of NOG-established cancer lines into NOG mice and morphologically observed the resulting tissue organization. As a result, the non-human animal models were demonstrated to exhibit pathologies (the hierarchical organization, cancer progression process, or biological properties of the cancer cells) similar to that of human cancer. Specifically, the present inventors succeeded in preparing non-human animal models exhibiting pathologies more similar to a human cancer, and cell culture systems using NOG-established cancer cell lines where the in vitro cell morphology is more similar to that of human cancer.

  • Patent number: 11124773
    Abstract: The purpose of the present invention is to provide: 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. For achieving the purpose, the present inventors grew a human cancer tissue repeatedly in a NOG mouse, separated cancer cells from the grown cancer tissue, and made a comparison of various cancer cell culture processes with each other. 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, and consequently the present invention has been accomplished.

  • Patent number: 10999478
    Abstract: An image processing apparatus includes a receiver and a correcting unit. The receiver receives a first read value and a second read value. The first read value indicates a result of reading a first color by a reader from a recording medium in which the first color is applied to a first area in which in-plane density unevenness is confirmable within the recording medium. The second read value indicates a result of reading a second color by the reader. The second color is different from the first color and is applied to a second area that is substantially the same as the first area in a superimposed manner. The correcting unit corrects in-plane density unevenness of the second color applied to the first color in the superimposed manner based on the first read value received by the receiver and the second read value received by the receiver.
