Cancer 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 کاملLanguages adapt to their contextual niche
Acknowledgements: We would like to thank Sean Roberts and two anonymous reviewers for feedback on an earlier draft of this manuscript. JW is funded by an AHRC studentship. Abstract It is well established that context plays a fundamental role in how we learn and use language. Here we explore how context links short-term language use with the long-term emergence of different types of language sys...
متن کاملStem cell researchers find their niche.
The EuroSTELLS Workshop ;Stem Cell Niches', organised by Anna Bigas, Ernest Arenas and Pasqualino Loi, took place in January 2008 in Barcelona, Spain. The goal of the conference was to promote scientific collaboration and synergy between stem cell researchers worldwide and those in the EuroSTELLS consortia (an initiative of the European Science Foundation EUROCORES Programme), and to stimulate ...
متن کاملHow children build their morphosyntax: the case of French.
Early morphosyntax is very rich and uniform in young French-speaking children. The present study aims to give a thorough analysis of the morphosyntax produced at the outset of multi-word speech, with a classification of free language produced at 2;0 by 27 French-speaking children. The corpus was fully tagged by an automatic part-of-speech tagger. A classification performed with words taken in i...
