Figure 7: BayesTME reveals gradual tumor invasion and confirms interface programs in a second zebrafish melanoma model.

A. Histology of the zebrafish B sample; cutout: tumor interface with the gradual invasion of tumor cells into the muscle region; bottom: corresponding tumor-muscle interface with tumor/non-tumor proportions capturing the gradient of tumor invasion present in histology. B-C. BayesTME discovers 10 cell types with their proportions and biologically plausible marker genes. D. 16 spatial transcriptional programs discovered at a 5% FDR.
