Supplementary information

Supplementary Video 1

3D malignant colorectal adenocarcinoma consisting of 50 slide images with an interslice distance of 20 μm digitized twice at 20x, once with an H&E stain and a second time with a Pan-cytokeratin immunohistochemical stain to reveal the epithelium in brown. Data related to Figure 2.

Supplementary Video 2

3D reconstruction of the isolated tumor class of a formalin-fixed paraffin-embedded colorectal carcinoma specimen processed using Knife-Edge Scanning Microscopy (KESM) technology and segmented using deep learning. Data related to Figure 3.

Supplementary Video 3

3D reconstruction of invasive ductal carcinoma lesion in a patient sample (30 µm Z-stack, 5 µm step). Collective strands of carcinoma cells were detected by positive E-cadherin staining; collagen bundles (SHG); nuclei (DAPI). The video is representative for 7 independent samples. Data related to Figure 5.

Supplementary Video 4

3D reconstruction of invasive lobular carcinoma lesion in a patient sample (60 µm Z-stack, 5 µm step). Collective strands of carcinoma cells were detected by positive staining for pan-cytokeratin; collagen bundles (SHG); nuclei (DAPI). The video is representative for 3 independent samples. Data related to Figure 5.
