  • Patent number: 10392602
    Abstract: Provided is a method of producing a lacrimal gland epithelial cell from a pluripotent stem cell, a lacrimal gland epithelial cell produced by the method, and a reagent kit for inducing differentiation from a pluripotent stem cell into a lacrimal gland epithelial cell. A method of producing a lacrimal gland epithelial cell includes the following step A: Step A: a step including increasing expression of Pax6 gene in a pluripotent stem cell or transfecting PAX6 protein thereinto, and increasing expression of Foxc1 gene or Foxp1 gene in the pluripotent stem cell or transfecting FOXC1 protein or FOXP1 protein thereinto.

  • Patent number: 10136203
    Abstract: To enhance positional accuracy of a speaker unit and to prevent sound leakage of sound outputted from the speaker unit and air leakage. Included are: a display configured to allow an image to be displayed on a display screen; a front board mounted on a front side of the display; a mount frame that is mounted on a rear surface side of the front board and includes a speaker mount section; a speaker bracket that is mounted on the speaker mount section and includes a sound output hole; and a speaker unit that is attached to the speaker bracket and includes a sound output section. The speaker mount section is provided with an insertion hole. The front board is provided with a mount hole superposed on the insertion hole. The speaker bracket is provided with a mount protrusion that is inserted in the insertion hole and the mount hole and is positioned with respect to the mount hole. The speaker bracket is provided with a sealing cushion located around the sound output section.

  • Publication number: 20180000915
    Abstract: Isolated IMP-3-derived epitope peptides having Th1 cell inducibility are disclosed herein. In preferred embodiments, such a peptide of the present invention can promiscuously bind to MHC class II molecules and induce IMP-3-specific cytotoxic T lymphocytes (CTLs) in addition to Th1 cells. Such peptides are thus suitable for use in enhancing immune response in a subject, and accordingly find use in cancer immunotherapy, in particular, as cancer vaccines. Also disclosed herein are polynucleotides that encode any of the aforementioned peptides, APCs and Th1 cells induced by such peptides and methods of induction associated therewith. Pharmaceutical compositions that comprise any of the aforementioned components as active ingredients find use in the treatment and/or prevention of cancers or tumors.
