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.

Method for displaying cell count information, system, and computer-readable medium

A method for assisting in cell isolation from a biological tissue section includes: obtaining cell images that are each an image of cells isolated from the biological tissue section, the biological tissue section being soaked in a solution containing an enzyme; calculating, from the cell images, a number of the cells isolated from the biological tissue section as an indicator of the cell isolation from the biological tissue section; and visualizing a temporal change in the indicator on the basis of a history of the indicator.

A cell analyzing device includes a control circuit. The control circuit acquires data of an observation image. The control circuit specifies a colony of a cultured cell in the observation image. The control circuit calculates a ratio at which the cultured cell occupies a predetermined range included in the observation image as an occupancy rate. The control circuit calculates a size of the colony. The control circuit determines a state of the cultured cell based on the occupancy rate and the size of the colony.

Cell analyzing device and cell analyzing system

An observation system includes a processor. The processor manages a plurality of images acquired in time series with respect to a biological sample which is being cultured, records a first comment and a first region of interest (RoI) in a storage device in association with the images based on user's instructions, and records a second comment and a second ROI in the storage device in association with the first comment based on user's instructions.

Observation system and information management method

A culture information processing device includes: a feature value computing unit that computes growth feature values indicating features of growth characteristics of cells from data acquired in a particular first subculturing process selected from among a plurality of subculturing processes included in a culture period of the cells; a condition setting unit that sets culturing conditions of a second subculturing process one process after the first subculturing process; and an information computing unit that computes, on the basis of the growth feature values computed by the feature value computing unit and the culturing conditions set by the condition setting unit, characteristics-related information related to growth characteristics in the second subculturing process.

Culture information processing device

An image reproducing device includes one or more processors. The processor acquires image group data including a plurality of images and tag information on at least one tag. The images relate to a biological sample along time series. The tag information relates to an operation on the biological sample and is associated with at least part of the images. The processor selects from the plurality of images using the tag information, images to be reproduced along the time series as reproduction selected images. The processor outputs to a display, data relating to the images for the reproduction selected images to be reproduced along time series.
