title: Adult stem cells and cancer stem cells: tie in or tear apart?
abstract: Stem cell research is one of the new frontiers of medical science. Because of the unique self-renewable ability and powerful potential to differentiate, stem cells can be viewed as the mother of all cells in the body and have been investigated as a possible tool for reversing the degeneration and damage on organs. Recently, successful isolating cancerous stem cells from leukemia, breast and brain cancers provide a new target for eliminate cancer; however, it hints an increasing caution in using adult stem cells for organ repair. Cancerous stem cells share the same properties of self-renewal and differentiation with normal stem cells, with the addition of similar phenotype of adult stem cells isolated from the same tissue. Some believe that cancerous stem cells are derived from mutation of the normal stem cells, whereas others suspect it to be from different origins. Further investigation of the intrinsic factor underlying the behavior of adult stem cells and cancerous stem cells will shed light on both the fields of tissue engineering and cancer therapy. In this review, recent progresses in the studies of adult stem cells and cancerous stem cells are summarized to facilitate a better understanding and elicit much attention in this field.
