The Dynamic Duo: Niche/Stem Cell Interdependency
Most tissues in our bodies undergo constant cellular turnover. This process requires a dynamic balance between cell production and elimination. Stem cells have been shown in many of these tissues to be the major source of new cells. However, despite the tremendous advances made, it still remains unclear how stem cell behavior and activity are regulated in vivo. Furthermore, we lack basic unders...
متن کاملNormal stem cells and cancer stem cells: the niche matters.
Scientists have tried for decades to understand cancer development in the context of therapeutic strategies. The realization that cancers may rely on "cancer stem cells" that share the self-renewal feature of normal stem cells has changed the perspective with regard to new approaches for treating the disease. In this review, we propose that one of the differences between normal stem cells and c...
متن کاملMotor proteins: A dynamic duo
The interactions between the microtubule motor cytoplasmic dynein and its putative regulator dynactin have been shown to be dynamic and complex.
متن کاملneoplastic bone marrow niche: hematopoietic and mesenchymal stem cells
the neoplastic niche comprises complex interactions between multiple cell types and molecules requiring cell-cell signaling as well as local secretion. these niches are important for both the maintenance of cancer stem cells and the induction of neoplastic cells survival and proliferation. each niche contains a population of tumor stem cells supported by a closely associated vascular bed compri...
متن کاملStem cells: So what's in a niche?
Much effort is being invested in defining the intrinsic and extrinsic factors that control stem cell maintenance and proliferation. Recent studies have identified a signaling hierarchy involved in coordinating the proliferation of germ line and somatic stem cells in the Drosophila ovary.
