A cell culture apparatus including cell culture units U and a measurement part (5). The measurement part (5) is provided with an imaging part (51) and is disposed so as to be capable of moving up and down between a back panel part (21) of a casing (2) and a culture container accommodating shelf (32). When the measurement unit (5) reaches a measurement position of each cell culture unit U which is a measurement subject, the culture container accommodating shelf (32) slides toward the measurement unit (5) so that portions to be measured of culture containers U20, U30 in each cell culture unit U come in an imaging range of the imaging part (51).

An illuminator includes a light source and an illumination optical system for causing light emitted from the light source to be incident on a sample surface where an imaging object is present. The illumination optical system has an optical axis coaxial with that of an imaging optical system. An image of the light source is formed between the illumination optical system and the imaging optical system. A holder arranges the sample surface between the light source image and the imaging optical system.

A system and method are provided for harvesting target biological substances. The system includes a substrate and a first and second channel formed in the substrate. The channels longitudinally extending substantially parallel to each other. A series of gaps extend from the first channel to the second channel to create a fluid communication path passing between a series of columns with the columns being longitudinally separated by a predetermined separation distance. The system also includes a first source configured to selectively introduce into the first channel a first biological composition at a first channel flow rate and a second source configured to selectively introduce into the second channel a second biological composition at a second channel flow rate. The sources are configured to create a differential between the first and second channel flow rates to generate physiological shear rates along the second channel that are bounded within a predetermined range.

[Problem] To evaluate objective cell groups by estimating a mixing ratio of objective cell group without affecting treatment itself and its production process when the objective cell groups include plural kinds of cell groups having different attributes, and to provide an image analysis system and a culture management system capable of accurately perform a quality control and a production control with low cost. [Solution] The cell quality evaluation system 1 detects a feature amount in each cell easily analyzable from images, and estimates a mixing ratio of each of plural kinds of cell groups included in the objective cell groups based on a distribution of the detected feature amount and pre-recorded information of the feature amount. As the feature amount, the embodiment uses a migration speed of each cell, easily distinguishable by analyzing tracking of each cell from plural images in time series.

An observation apparatus, an observation method, and an observation program capable of capturing an image by appropriately adjusting a focus regardless of a size of an effective range in which a distance to a cultivation container can be measured within a field of view are provided. An observation apparatus includes an imaging unit 37 that images an observation target in a field of view smaller than an accommodation part 22 at a series of imaging positions and acquires a series of partial images, a measurement unit 38 that measures a distance from the imaging unit 37 to the accommodation part 22, a storage unit 44 that stores shape information of a container 20 and a series of imaging position information, a calculation unit 45 that calculates effective range information indicating an effective range in which the measurement unit 38 is capable of performing measurement before imaging within a field of view of the imaging unit 37 at the imaging positions, based on the shape information and the imaging position information, and a control unit 40 that controls a focus of the imaging unit 37 using a measurement result measured by the measurement unit 38 in the effective range and a measurement result of the measurement unit 38 in a field of view adjacent to the field of view including the effective range in a case where the effective range is smaller than or equal to a threshold value.

A method for dynamic evolution and/or adaptation and monitoring of characteristics in living cells is provided, wherein the method may be performed at a microfluidic-enabled cell-culture device comprising pneumatic layer for directing flow of fluid to a plurality of individually addressable wells, and one or more sensors configured to detect data regarding environments inside one or more of the plurality of wells. The method may involve culturing a population of cells in a first well of the plurality of wells, perturbing one or more characteristics of an environment in the first well following the culturing of the population of cells, monitoring one or more characteristics of the population of cells in the first well, and removing all or part of the evolved/adapted population of cells from the first well.

The cell evaluation device includes a cell housing unit 111, and an adapter 120 configured to be elastically deformed by being fitted into the cell housing unit to close a top opening of the cell housing unit, and the adapter includes a body 121 to be inserted into the cell housing unit, a positioning unit 122 configured to position the body in a vertical direction with respect to the cell housing unit, a culture medium inlet port 124 and a culture medium outlet port 125 penetrating the top end and the lower end of the body, and a flexible sheet member 123 which is provided on a lower end of the body and extends radially outward from an outer edge of the lower end. This makes it possible to prevent leakage of the culture medium in the cell evaluation device.

An information processing apparatus includes an acquisition unit that acquires an evaluation value for a state of cells which are cultured in each of a plurality of fluidic devices, culture environment, and information representing a disposition position of the fluidic device; and a generation unit that generates a learned model in which the evaluation value and the information representing the disposition position are received as an input and the culture environment is output, through machine learning using, as training data, the evaluation value before adjustment of the culture environment, the culture environment after the adjustment, and the information representing the disposition position, in a case where, due to the adjustment, the evaluation value becomes a first threshold value or more and an absolute value of a difference in evaluation value between the plurality of fluidic devices becomes a second threshold value or less.
