    摘要: A cell observation apparatus includes a cell recognition unit that recognizes a cellular region representing a cell from cell image data acquired by imaging the cell at a plurality of time points; and a cell parameter measurement unit that measures cell parameters characteristic of the cellular region recognized by the cell recognition unit. The apparatus also includes a cell viability determination unit that determines cell viability by comparing the cell parameters measured by the cell parameter measurement unit with thresholds.

    摘要: The invention provides ion-selective sensors comprising quantum dots capable of selectively measuring ions, e.g., Na+, K+, Cl−, etc., in various environments, including in the cytosol of a living cell. Quantum dots are attractive probes for microscopy due to their photophysical advantages over fluorescent dyes, including prolonged photostability, brightness and quantum efficiency. In certain embodiments, a sensor comprises one or more quantum dots, a pH-sensitive dye, and optionally an ion-selective component such as an ionophore. These elements may, for example, be disposed in a polymer matrix. In certain embodiments, the sensors may detect ionic analytes by selective ion extraction by the polymer, thereby inducing a pH change within the sensor which in turn changes the absorbance of the pH-sensitive dye. The change of absorbance may in turn attenuate the intensity of detectable emissions, e.g., fluorescence, from the quantum dot by directly absorbing its fluorescence emission.

    摘要: The present invention provides methods for producing hematopoietic stem cells or vascular endothelial precursor cells, wherein the methods comprise the step of separating PCLP1-positive cells from the hematopoietic tissues of an individual, and then culturing the obtained cells. PCLP1-positive cells obtained from the hematopoietic tissues of an individual can be cultured for a long time, and during culture they produce large quantities of hematopoietic stem cells or vascular endothelial precursor cells. The hematopoietic stem cells or vascular endothelial precursor cells obtainable by the present invention can be utilized for regenerative medicine.

    摘要: A microdroplet test apparatus for use in HLA typing. The apparatus is an improvement upon the well known Terasaki tray which is in use for determining HLA antigens by measuring lymphocyte cytotoxicity. The apparatus includes a tray having a plurality of microtest wells wherein the sides of the microtest wells are designed to promote localization of lymphocytes or other cells being tested at the microtest well bottom. The apparatus further includes a cover having either rods or tubes which extend down into the test solution present in the microtest well to thereby control the amount of test solution which is present in the cylindrical optical view path through which the test solution is viewed by microscope for test result measurements. This allows control of the amount of test solution in the optical view path in order to reduce the amount of solution which must be looked through when cells are being counted or alternatively, increasing the amount of test solution present in the view path in order to maximize detection when a colored reaction product in the test solution is being measured.
