Abstract

Cancer stem cells (CSCs) are considered to be the origin of cancer relapse and metastasis. The better understanding of CSCs, including CSCs in human colorectal cancer (CRC), may facilitate prevention and treatment. This study aimed to establish a CSC enrichment model via the induction of epithelial-mesenchymal transition (EMT) in CRC cells. We established an EMT model using the SW480 CRC cell line by CDH1 knockdown using shRNA interference. CD24+CD44+ cells were enriched in the CDH1 knockdown cells. The cells exhibited mesenchymal morphology and expressed high levels of EMT-related proteins, which confirmed that these cells had undergone EMT. Our results further showed that the proliferation rate of the transfected cells was reduced, whereas their colony-forming capacity and tumorigenesis in vivo was significantly enhanced compared to the control cells. In conclusion, these cells were highly enriched CSCs (compared to normal CSCs) and may be used as a stable model for cancer research and anticancer drug screening.
