Extended Data Fig. 2: AI Modeling of Tumor and Stroma.

(a) H&E slide with the tumor area and regions of interest (ROIs) marked by pathologist (WT). Frames of selected regions were box-outlined and saved in a database file to assure reproducibility of the experiment.; b) Same area with the cancer cells mask (cyan) predicted by our AI model. Segmentation of cancer mask by DeepLabV3Plus was performed 10 times. Each time the exact same mask was outputted. Scale bar is 1mm.
