    • PROBLEM TO BE SOLVED: To provide a method for screening an unerring therapeutic agent for dementia at an individual level.SOLUTION: A transgenic non-human animal in which a dementia-related gene is expressed is created by introducing an expression vector carrying the dementia-related gene into the inner ear hair cells of a non-human animal being a test subject. A candidate compound is administered to a transgenic non-human animal in which the dementia-related gene is expressed. Sense of hearing of the transgenic non-human animal in which the candidate compound is administered is detected. In such a case where the degree of hearing disorder in a transgenic non-human animal in which a candidate compound is administered is more dissolved than the degree of hearing disorder in a transgenic non-human animal in which a candidate compound is not administered, the candidate compound is determined to be effective as a therapeutic agent for dementia.
    • 待解决的问题:提供一种用于在个体水平上筛选痴呆治疗剂的方法。 解决方案:通过将携带痴呆相关基因的表达载体导入作为受检对象的非人动物的内耳毛细胞来产生其中表达痴呆相关基因的转基因非人动物。 将候选化合物施用于其中表达痴呆相关基因的转基因非人动物。 检测其中施用候选化合物的转基因非人动物的听觉。 在其中施用候选化合物的转基因非人动物中的听觉障碍程度比没有施用候选化合物的转基因非人动物中的听力障碍程度更多的情况下, 候选化合物被确定为有效作为痴呆症的治疗剂。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To demonstrate that a mesenchymal stem cell sheet has therapeutic potential for a severely damaged heart due to its pluripotency and in situ self-renewal capability, while mesenchymal stem cells are pluripotent cells capable of differentiating into myocardial and vascular endothelial cells.SOLUTION: The mesenchymal stem cells derived from adipose tissue are cultured to prepare the mesenchymal stem cell sheet. Four weeks after induction of myocardial infarction in rats, the mesenchymal stem cell sheet is transplanted to the heart. The mesenchymal stem cell sheet is readily engrafted to the surface of the scarred myocardium, grew gradually in situ, and formed a thick layer (approximately 600 μm) in the four weeks. The grown transplanted mesenchymal tissue contains newly formed blood vessels, myocardial cells, and undifferentiated mesenchymal cells. The engrafted mesenchymal stem cells inhibits thinning of the myocardial wall in the scar area, and improves cardiac function and survival rate in the rats with myocardial infarcts.
    • 待解决的问题:为了证明间充质干细胞片由于其多能性和原位自我更新能力而对严重损伤的心脏具有治疗潜力,而间充质干细胞是能够分化为心肌和血管的多能细胞 内皮细胞。 解决方案:培养源于脂肪组织的间充质干细胞以制备间充质干细胞片。 诱导大鼠心肌梗塞后4周,将间充质干细胞片移植至心脏。 间充质干细胞片容易移植到瘢痕性心肌的表面,在原位逐渐生长,并在四周内形成厚层(约600μm)。 生长的移植间质组织包含新形成的血管,心肌细胞和未分化的间充质细胞。 移植的间充质干细胞抑制瘢痕区域心肌壁变薄,改善心肌梗死大鼠的心脏功能和存活率。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an antibody capable of detecting Hzf protein, to provide a hybridoma capable of producing the antibody, and to provide a cell fusion method for producing the hybridoma. SOLUTION: The hybridoma is obtained by cell-fusing the antibody-producing cell of a mammal immunized by LHPAPGPIRTAHGPILFSPY with the myeloma cell of a mammal. The hybridoma is deposited as receipt number NITE AP-853 to Independent administrative agency, Product evaluation technical substrate mechanism, International Patent Organism Depositary, or as receipt number NITE AP-854 to Independent administrative agency, Product evaluation technical substrate mechanism, International Patent Organism Depositary. The antibodies produced from the hybridomas can be detected by immunoblotting Hzf protein, immunoprecipitation method, and cellular immune dyeing method. COPYRIGHT: (C)2011,JPO&INPIT
