  • Publication number: 20220155213
    Abstract: An erythrocyte differentiation monitoring apparatus includes a laser light source that radiates a pulsed laser beam in a hemoglobin absorption wavelength range onto a cell within a culture container, a probe that receives a photoacoustic wave emitted from the cell within the culture container as a result of the cell being irradiated with the pulsed laser beam emitted from the laser light source, and a processor that evaluates the progress of differentiation of the cell into an erythrocyte based on the intensity of the photoacoustic wave received by the probe.

  • Publication number: 20220146404
    Abstract: A method for displaying cell count information includes steps for: obtaining a cell image; obtaining a first cell count output by applying the cell image to a first counting model; obtaining a second cell count output by applying the cell image to a second counting model; and displaying, on the basis of the first and second cell counts, a screen on which at least either of the first and second cell counts and a correlation between the first and second cell counts are visualized. The first counting model is different from the second counting model.

  • Publication number: 20220130043
    Abstract: A method for evaluating an adherent cell includes: obtaining an image of an adherent cell accommodated within a culture container; and determining whether the adherent cell is adhering to the culture container based on at least a profile shape of a contact portion of the adherent cell that is in contact with the culture container, the profile shape being specified from the image.

  • Publication number: 20220109786
    Abstract: An endoscope system includes an endoscope including an insertion unit and a sensor. The sensor is disposed at a distal end of the insertion unit. The sensor unit includes a motion sensor and a light source. The motion sensor is configured to execute a measurement operation and generate a measurement value indicating a measurement result. The light source is configured to generate light indicating the measurement operation at a timing that is synchronized with the measurement operation. The insertion unit includes an imaging device disposed at the distal end and configured to receive the light generated by the light source and generate an image.

  • Publication number: 20200311922
    Abstract: An cell observation system, comprising an image sensor capable of movement in a horizontal direction, and a processor, wherein the processor infers position where a colony will be generated or grown from position information or shape information of a plurality of cells within an image, based on the image of the cells that has been acquired by the image sensor, and controls position of the image sensor so as to perform imaging at the inferred position.

  • Publication number: 20200224142
    Abstract: The frequency at which a culture medium is replaced is reduced by prolonging the service life of the culture medium, the size of a device is reduced, cost is reduced, and a mechanical strength is enhanced. Provided is a cell culture device including: a culture container capable of accommodating cells and a culture solution; and an adsorbing member that is formed of a porous material having adsorption holes, the hole diameters of which are smaller than the cells and larger than impurities in the culture solution, and that adsorbs the impurities, without adsorbing the cells, in the culture solution by means of the adsorption holes while at least a portion of the adsorbing member is immersed in the culture solution in the culture container.
