(A) The exfoliome signature arises from cells sloughed from both the small intestine and colon and comprises reads from the diverse array of cell types expected to be found in the intestinal mucosa (A) Heatmap showing counts of genes that are reported to be primarily expressed at specific anatomic locations (stomach, pancreas, small intestine, colon). All genes with counts greater than 400 are colored dark blue. (B) Heatmap showing counts of biomarker genes from each sample and each data source (orange = gene not expressed).
