Microbiota phenolic-derived metabolites can battle colon cancer stem cells (CSCs).
Urolithins (Uros) and ellagic acid (EA) inhibit CSC features in vitro and ex vivo.
Mixed Uros and EA inhibit the formation and growth of colonospheres.
Mixed Uros and EA reduce ALDH-expressing cell population of CSCs.
Potential effect of Uros on the recurrence and chemoresistance of colon cancer.
