(a) Fingerprint analysis of cases HROC107 and HROC131. The alleles of nine classical markers are displayed. No differences were observed between the original tumor and both the PDX models and the tumor cell lines generated from the 24 h PDX models.

(b) The results of the molecular analysis of cases HROC107 and HROC131 (according to [3]) are displayed. Mutations in the CRC-relevant target genes p53, APC, K-, N-, and H-Ras, PIK3CA, and B-Raf were analyzed. Together with the CIMP and MSI analysis results, the underlying molecular type could be identified as spSTD for HROC107 and spMSI-H for HROC131.

ID: pseudonym of case, sex: result of the amelogenin marker analysis, m: male, f: female, sp: sporadic, Std: standard type, Ex8: exon number 8, mut: mutated, wt: wild type, n.a.: not analyzed, CIMP: CpG island methylator phenotype, MSI: microsatellite instability, MSS: microsatellite stable, MSI-H: high grade microsatellite instable.
