  • Publication number: 20240135541
    Abstract: A microscope image of a cultured cell cluster derived from a cancer specimen of a patient is acquired. A measured value of a gene expression level of the cluster is acquired. Based on the image, a morphological representation identifiably expressing, by a vector quantity of a plurality of dimensions, a morphological difference between a group of cell clusters cultured from the same cancer specimen and a group of cell clusters cultured from another cancer specimen is acquired. The acquired morphological representation is input to a function, which is obtained by fitting the measured value with respect to the morphological representation, to acquire a prediction value of the gene expression level. Prediction accuracy is estimated based on the prediction value and the measured value. Based on the estimated prediction accuracy, a gene related to a morphological change of the cell cluster is extracted as a gene candidate.
