[Problems]To provide a microchip for cell arranging which transfers and arranges the cell accurately and quickly, by combining advantages of the method of an optical tweezer and of micro channel.[Means for Solving Problems]A microchip for arranging cells, including a base, the base comprising: at least one cell supply channel including a cell inlet port in liquid communication with a supply mechanism configured to supply the cells into the cell supply channel; at least one cell drain channel including a cell drain port in fluid communication with a drain mechanism, the cell drain channel configured to guide the cells to the cell drain port; at least one reservoir for temporarily storing the cells flowing between the cell supply channel and the cell drain channel; at least one cell arrangement portion for receiving cells introduced from the reservoir, the cell arrangement portion comprising plural compartments partitioned by a wall; and at least one junction channel extending from the cell arrangement portion to the reservoir; wherein the reservoir is wider than the cell supply channel, the cell drain channel and the junction channel.
摘要:
The present invention provides a therapeutic agent for Alzheimer's disease. The therapeutic agent contains membrane vesicles (exosomes) of adipose tissue-derived mesenchymal stem cells, and the membrane vesicles (exosomes) contain neprilysin. Through the research by the inventors of the present invention, it was revealed that exosomes secreted by human adipose tissue-derived mesenchymal stem cells contain neprilysin, which degrades amyloid-β as a pathogenic protein of Alzheimer's disease. When exosomes secreted by human adipose tissue-derived mesenchymal stem cells were administered to the brains of Alzheimer's disease model mice, the generation of amyloid-β was inhibited.

摘要:
Objects to be achieved by the invention are to provide a nanobio device in which cultured cells are organized at a high-level in a state near in vivo, and to provide a method of using the nanobio device of imitative anatomy structure. The nanobio device of imitative anatomy structure of the invention is obtained by manufacturing a substrate with a bio-compatible substance and arranging a plurality of types of cells thereon in a desired array. A method of manufacturing a nanobio device in the invention includes a step of manufacturing a substrate for a nanobio device by a micromachine processing technique and a step of arranging a plurality of cultured cells on the substrate in a desired array with laser optical tweezers.
摘要:
The present invention concerns methods and compositions for identifying genes or genetic pathways modulated by miR-16, using miR-16 to modulate a gene or gene pathway, using this profile in assessing the condition of a patient and/or treating the patient with an appropriate miRNA.

摘要:
The present invention provides a human c-Ha-ras proto-oncogene transgenic rat and the methods of the screening of many carcinogens and the screenings of promoters of carcinogenesis and preventive and inhibitory agents of tumors, and additionally enables the analysis of the carcinogenesis mechanism of a number of tumors.
摘要:
The present invention provides a preparation method of a chimeric embryo and a chimeric rat, which is characterized by contacting a rat pluripotent stem cell and a host embryo in the presence of an ES cell differentiation inhibitor. The method includes (a) a step for contacting a fertilized host embryo collected from a female rat and a rat pluripotent stem cell in the presence of an ES cell differentiation suppressant, and (b) a step for culturing the host embryo in contact with the rat pluripotent stem cell to form a chimeric embryo.
