Isolation and characterization of potential cancer stem cells from solid human tumors--potential applications.

Isolation and characterization of potential cancer stem cells from solid human tumors--potential applications. Curr Protoc Pharmacol. 2013;63:Unit 14.28. Authors: Dobbin ZC, Landen CN Abstract Cancer stem cells (CSCs) are a subpopulation of cells within a heterogeneous tumor that have enhanced biologic properties, e.g., increased capacity for self-renewal, increased tumorigenicity, enhanced differentiation capacity, and resistance to chemo- and radiotherapies. This unit describes protocols to isolate and characterize potential cancer stem cells from a solid tumor. These involve creating a single-cell suspension from tumor tissue, tagging the cell subpopulations of interest, and sorting them into different populations. The sorted subpopulations can be evaluated for their ability to meet the functional requirements of a CSC, which primarily include increased tumorigenicity in an in vivo xenograft assay. Use of the protocols described in this unit makes it possible to study populations of cells that may have properties of CSCs. PMID: 24510756 [PubMed - indexed for MEDLINE]
