h repeat-containing G-protein-coupled receptor 5 (LGR5) is a promising intestinal stem cell and carcinoma stem cell marker. We examined the relationship between mismatch repair (MMR) protein deficiency and LGR5 expression in poorly differentiated (PD) colorectal carcinoma (CRC). | Characterization of LGR5 expression in poorly differentiated colorectal carcinoma with mismatch repair protein deficiency
