Fig. 4From: Evolution of intra-tumoral heterogeneity across different pathological stages in papillary thyroid carcinomaMutational signatures in different stages of PTC. Barplot shows the weighted contributions of mutation signatures in the 4 tumor stages. Bars colors indicate the 4 tumor stages. Vertical axes depict the mutational signature frequency in each tumor stage. Signatures indicate as “unknown” has an undetermined etiology (see “Results” section for more details)Back to article page
