Summary: Colon cancer is a heterogeneous tumor driven by a subpopulation of cancer stem cells (CSCs). To study CSCs in colon cancer. we used limiting dilution spheroid and serial xenotransplantation assays to functionally define the frequency of CSCs in a panel of patient-derived cancer organoids. These studies demonstrated cancer organoids to be enriched for CSCs. https://www.ealisboa.com/best-flash-Nightstick-TWM-850XL-Tactical-Weapon-Mounted-Light-limited-super/
