Microenvironmental interactions and expression of molecular markers associated with epithelial-to-mesenchymal transition in colorectal carcinoma.

The tumor microenvironment is known to play a critical role in tumor progression, invasion and metastasis. The epithelial-to-mesenchymal transition (EMT) is understood as a process of tumor invasion and metastasis. Therefore, we investigated the relation between the EMT and the microenvironment of colorectal carcinoma (CRC).
