Abstract
Image analysis methods and apparatus are used for determination of the ploidy of cells. The methods may involve segmenting an image to identify one or more discrete regions occupied by cells or nuclei, determining the presence of a particular ploidy indicator feature within the region(s), and providing a value of the indicator feature to a model that classifies cells' ploidy on the basis of the indicator feature. In some embodiments, the indicator feature is a level of DNA in a cell. In certain embodiments, the method further comprises treating one or more cells with a marker that highlights the ploidy indicator feature. In certain embodiments, the cells are treated prior to producing one or more images of the one or more cells. In certain embodiments, the ploidy indicator feature comprises DNA and the marker co-locates with DNA and provides a signal that is captured in the image. In certain embodiments, the signal comprises a fluorescent emission.
