Stem cells and their niche: an inseparable relationship.
A recent Keystone symposium on 'Stem Cell Interactions with their Microenvironmental Niche' was organized by David T. Scadden and Allan C. Spradling. The meeting was held in conjunction with another Keystone symposium, 'Stem Cells and Cancer', at Keystone, Colorado. Among the work that was presented at this meeting, scientists presented data that advances our understanding of the contribution t...
متن کاملCancer Stem Cells and Their Niche
Stem cells within many tissues are thought to reside within a niche formed by a group of surrounding cells and their extracellular matrices, which provide an optimal microenvironment for the stem cells to function. In general, the niche is thought to consist of a highly organized microenvironment in which various factors, such as signals coming from secreted cytokines, extracellular matrix inte...
متن کاملCancer stem cells and their niche.
The unique characteristics of stem cells, specifically pluripotency and self-renewal, are critical for sustaining the lifelong functionality of organs. Stem cells reside in a special microenvironment called the niche. Stem cells interact with the niche via adhesion molecules and exchange molecular signals that maintain the specific features of stem cells. A better understanding of the nature of...

متن کاملDrug Resistance Driven by Cancer Stem Cells and Their Niche
Drug resistance represents one of the greatest challenges in cancer treatment. Cancer stem cells (CSCs), a subset of cells within the tumor with the potential for self-renewal, differentiation and tumorigenicity, are thought to be the major cause of cancer therapy failure due to their considerable chemo- and radioresistance, resulting in tumor recurrence and eventually metastasis. CSCs are situ...
