Resumen

The heterogeneity of breast tumors is a major factor in the development, progression, and therapeutic response of breast cancer. In terms of therapy resistance, a subset of tumor cells commonly referred to as cancer stem cells (CSCs) or tumor initiating cells (TICs) have a prominent role. These cells have inherent increased tumorigenicity, self-renewal and differentiation capacity, and mechanisms for chemotherapy and radiation resistance. The importance of CSCs/TICs in cancer makes isolating and studying these cells via reliable methods critical. CSCs/TICs can be enriched for by discrete markers. Increased aldehyde dehydrogenase (ALDH) activity as detected by the Aldefluor^TM assay is a commonly used method. In this chapter, we describe the detailed methods for identification and isolation of putative CSCs/TICs from cultured cells and xenografted breast tumors using the Aldefluor^TM assay and describe the importance of the ALDH isoforms in breast cancer.
