WSI, whole slide image; ESD, endoscopic submucosal dissection; LGD, Low-Grade Dysplasia; HGD, High-Grade Dysplasia; CRP, Colorectal project.

^a Four splenic Neuroendocrine Tumors (NETs), four pancreatic NETs, five soft tissue-bone tumors, and ten breast tumors.

^b The number in the parentheses represents the number of ROIs validated in the WSIs (20 ROIs in 4 images were validated and scored by external validators in the mitosis project).

^c Colon Resection specimens were prepared as Whole Mount Slides, scanned by S60 and p1000 scanners, and trained, tested, and validated as WMIs. Some of the same slides were trained for different layers in the project.
