Fig. 2From: Spatio-temporal mutation profiles of case-matched colorectal carcinomas and their metastases reveal unique de novo mutations in metachronous lung metastases by targeted next generation sequencingMorphology and tNGS amplicon coverage of investigated primary tumours and distant metastases of the CRC cases. a The panels depict H&E sections of case-matched primary tumours, and synchronous and/or metachronous liver or lung metastasis of three representative cases. Note areas of necrosis (“nec”; e.g. case #8, synM(HEP)) and widely distributed clusters of few tumor cells (e.g. case #6, metM(HEP)), necessary for interpretation of gene mutations with lower allele frequencies. All panels same magnification 2.5x except case #6 metM(HEP) being 10x. b Summary of the amplicon coverage for all 70 investigated DNA samples of the CRC cohort.
