摘要： Image analysis methods and apparatus are used for distinguishing live and dead cells. The methods may involve segmenting an image to identify the region(s) occupied by one or more cells and determining the presence of a particular live-dead indicator feature within the region(s). In certain embodiments, the indicator feature is a cytoskeletal component such as tubulin. In certain embodiments, the methods may involve determining the value of an indicator expression that is based on cellular components such as DNA and/or cellular protein. Prior to producing an image for analysis, cells may be treated with a marker that highlights the live-dead indicator in the image.

In certain embodiments, the indicator feature is a cytoskeletal component such as tubulin. Prior to producing an image for analysis, cells may be treated with a marker that highlights the live-dead indicator in the image. In the case of tubulin, the marker will co-locate with tubulin and provide a signal that is captured in the image (e.g., a fluorescent emission).

摘要： A method for calculating distances between stimulus response curves (e.g., dose response curves) allows classification of stimuli. The response curves show how the phenotype of one or more cells changes in response to varying levels of the stimulus. Each “point” on the curve represents quantitative phenotype or signature for cell(s) at a particular level of stimulus (e.g., dose of a therapeutic). The signatures are multivariate phenotypic representations of the cell(s). They include various features of the cell(s) obtained by image analysis. To facilitate the comparison of stimuli, distances between points on the response curves are calculated. First, the response curves may be aligned on a coordinate representing a separate distance, r, from a common point of negative control (e.g., the point where no stimulus is applied). Integration on r may be used to compute the distance between two response curves. The distance between response curves is used to classify stimuli.
摘要翻译：用于计算刺激响应曲线（例如，剂量响应曲线）之间的距离的方法允许对刺激进行分类。响应曲线显示了一种或多种细胞的表型如何响应刺激的不同水平而改变。曲线上的每个“点”表示特定刺激水平（例如，治疗剂的剂量）的细胞的定量表型或特征。签名是细胞的多变量表型表达。它们包括通过图像分析获得的细胞的各种特征。为了促进刺激的比较，计算响应曲线上的点之间的距离。首先，响应曲线可以在表示来自负控制的公共点（例如，不施加刺激的点）的单独距离r的坐标上对准。可以使用r上的积分来计算两个响应曲线之间的距离。响应曲线之间的距离用于对刺激进行分类。

摘要： Methods, apparatus, and computer programs for investigating and characterising side effects of a treatment having an intended or on-target effect on cells are described. The method can include identifying a group of on-target cellular features of the plurality of cells which are affected by the treatment and are related to the on-target effect. A group of off-target cellular features can also be identified which are different to the on-target cellular features and which are also affected by the treatment and which are related to the side effect. A measure of the side effect based on the off-target cellular features can be obtained. The treatment can then be characterised based on the measure of the side effect. A further method involves capturing an image of the population of treated cells and deriving cellular features from the image. An on-target effect signature, which is characteristic of the on-target effect is created from cellular features relating to cellular properties involved in the intended effect. A side effect signature, which is characteristic of a side effect to the on-target effect, is created using cellular features relating to cellular properties not involved in the intended effect. On-target effect and/or side effect metrics are obtained from the signatures which can be used to characterise the treatment.
