When transplanted into athymic mice, Coala cell line forms fast growing tumors with histological features similar to original tumor and expressed CDX2, SATB2, and CK20. Whole exome sequencing analysis of Coala cell line showed the presence of pathogenic mutations in C8B, PRKCQ, IRGM, FGFR4, POLR1C, APC and TP53 genes. Here, CDX2 is linked to neoplasm.
