ANALYZING THE EXPRESSION OF BIOMARKERS IN CELLS WITH CLUSTERS

摘要

A data set of cell profile data is stored. The cell profile data includes multiplexed biometric image data describing the expression of a plurality of biomarkers. Cell profile data is generated from tissue samples drawn from a cohort of patients having an assessment related to the commonality. Multiple sets of clusters of similar cells are generated from the data set; the proportion of cells in each cluster is examined for an association with a diagnosis, a prognosis, or a response; and a predictive set of clusters is selected based on model performance. One predictive set of clusters is selected based on a comparison of the performance of at least one model of the plurality of sets of clusters. Display techniques that aid in understanding the characteristics of a cluster are disclosed.

主权项

1. A method of analyzing cell cluster features based on multiplexed biometric images comprising:
storing a data set comprising cell profile data including multiplexed biometric images capturing the expression of a plurality of biomarkers with respect to a plurality of fields of view in which individual cells are delineated and segmenting into compartments; identifying a first cluster in a plurality of clusters of similar cells from the data set, wherein each cell is assigned to one of the plurality of clusters, wherein each cluster in the plurality of clusters includes cells having a plurality of selected attributes more similar to the plurality of selected attributes of other cells in that cluster than to the plurality of selected attributes of cells in other clusters in the set; creating a montage of a first cell in the first cluster, wherein the montage comprises a portion of at least some multiplexed images describing the first cell's expression of each of a plurality of biomarkers, wherein each portion of the at least some images includes the first cell and a small region of interest around the first cell; and displaying the montage of the first cell in the first cluster to enable a user to understand a feature of the first cluster.
