Figure 2From: LINE-1 methylation shows little intra-patient heterogeneity in primary and synchronous metastatic colorectal cancer Influence of stromal cell contamination of the tumor sample on results from the LINE-1 methylation assay. (A) LINE-1 methylation levels in tumor, stromal and normal cells. (B) LINE-1 methylation levels in microdissected tumor cells and in macrodissected tumor tissues. (C) Distribution of LINE-1 methylation levels in microdissected tumor cells (upper panel) and in macrodissected tumor tissues (lower panel).Back to article page
