    摘要: In the present invention, a cardiomyocyte cluster is disposed on a transparent substrate, and the quality of the cardiomyocytes is evaluated from the response of the cells to a forced pulsation stimulus applied to the cardiomyocytes. The cardiomyocyte cluster is disposed on the transparent substrate, and is exposed to the flow of a liquid containing an agent in a manner so that the agent acts on the cells, which configure a network. The extent of cardiac toxicity resulting from the agent is evaluated from measuring the fluctuations obtained from a comparison of adjacent cardiomyocytes of the network.

    摘要: A cell sorting device using an inexpensive chip capable of being exchanged for each sample. The chip includes: a first flow path allowing buffer fluid containing cells to flow down; second and third flow paths which put the first flow path therebetween and allow buffer fluid not containing cells to flow down; a fourth flow path which allows the buffer fluid as a single flow path formed by joining the buffer fluids in the other three flow paths; a cell detecting region for detecting cells flowing with the buffer fluid down the fourth flow path; and a cell sorting region for sorting the cells according to a type of the cells detected. The first to fourth flow paths are cascaded, are supplied with the buffer fluid from reservoirs with the same fluid level, and have substantially the same width or cross-section area.

    摘要: An inexpensive cell analysis and separation apparatus using a flow channel formed on one surface of a substrate and a chip replaceable for each sample, and a method for culturing the separated cells without contamination, are provided. A flow channel for allowing a cell-containing buffer solution to flow is provided. Cells are detected in the middle of the flow channel, and separated to a plurality of downstream flow channels based on whether each cell fulfills a predetermined condition. A culturing tank for collecting the condition-fulfilling cells is covered with a semipermeable membrane at a top surface so as to prevent contamination during cell separation. When the cell separation is finished, the flow channel communicated with the culturing tank accommodating the condition-fulfilling cells is closed, and the culturing tank is cut off from the apparatus and put into a culturing device containing a predetermined medium to culture the cells.

    摘要: A method of inspecting a DNA chip and an apparatus therefor that allow a picture to be reconstructed in the following steps: A plurality of irradiation spots are formed on a DNA probe array mounted on a stage. Then, the stage is displaced in X, Y directions so as to execute a scanning, thereby irradiating substantially all the entire surface of the DNA probe array. Next, a plurality of emitted fluorescent lights, which are generated from the plurality of irradiation spot portions on the DNA probe array, are converged and are then detected simultaneously by multi detectors. Finally, a data processing apparatus processes the detected signals, thereby reconstructing the picture.
