title: Profiling cancer stem cells using protein array technology.
abstract: Since cancer cells and somatic stem cells share the biological characteristics of self-renewal and proliferation, it has been suggested that the principles of stem cell biology can be applied to improve our understanding of cancer biology. Recent studies have shown that the majority of cancers appear to originate from a small subset of cells that have the ability of self-renewal and to proliferate, namely 'cancer stem cells'. The isolation of cancer stem cells has been demonstrated using cell surface markers in haematopoietic and non-haematopoietic malignancies. Advances in protein array technologies have enabled the use of minuscule amounts of biological materials to profile these cells at the molecular level. Using a combination of protein arrays and cancer stem cell isolation techniques, a higher resolution molecular profiling can be performed, which might improve therapies targeting the cancer stem cells.
