Gene expression profiling of leukemia stem cells

Abstract

Characterization of gene expression programs and pathways important for normal and cancer stem cells has become an active area of investigation. Microarray analysis of various cell populations provides an opportunity to assess genomewide expression programs to define cellular identity and to potentially identify pathways activated in various stem cells. Here we describe methods to isolate a leukemia stem cell population, amplify RNA, and perform microarray analyses. © 2009 Humana Press, a part of Springer Science+Business Media, LLC.
