Characterization of Side Population in Thyroid Cancer Cell Lines: Cancer Stem-Like Cells Are Enriched Partly But Not Exclusively

Abstract excerpt

There is increasing evidence that cancers contain their own stem-like cells called cancer stem cells (CSCs). A small subset of cells, termed side population (SP), has been identified using flow cytometric analysis. The SP cells have the ability to exclude the DNA binding dye, Hoechst33342, and are highly enriched for stem cells in many kinds of normal tissues. Because CSCs are thought to be drug resistant, SP...
