To establish if the mechanism mediating paracrine cellular communication that we uncovered is conserved in human colon cancer, we then analysed a cohort of 10 human colon tumours (five low-grade adenomas and five invasive carcinomas) for their expression of THBS1, LGR5, and YAP (Figure 6B–E). The gene discussed is LGR5; the disease is colonic neoplasm.
