The cancer stem cell hypothesis posits that cancer stem cells (CSCs) are the driving force behind tumour progression and metastasis, making them ideal therapeutic targets. Previous research identified Leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5) as a marker of CSCs in colorectal cancer (CRC). However, it is not known whether more than one CSC population exists in CRC. Identifying and targeting CSCs in CRC is important for effective treatment of cancer patients. Here, I show that Keratin-19 (K19) labels intestinal CSCs in mouse tumours that recapitulate the early stages of CRC. Moreover, selective ablation of Lgr5 has no effect on tumour …
