Stemness in Cancer: Stem Cells, Cancer Stem Cells, and Their Microenvironment [PDF]
Stem Cells International, 2017 Stemness combines the ability of a cell to perpetuate its lineage, to give rise to differentiated cells, and to interact with its environment to maintain a balance between quiescence, proliferation, and regeneration. While adult Stem Cells display these properties when participating in tissue homeostasis, Cancer Stem Cells (CSCs) behave as their ...

Stemming vision loss with stem cells [PDF]
Journal of Clinical Investigation, 2010 Dramatic advances in the field of stem cell research have raised the possibility of using these cells to treat a variety of diseases. The eye is an excellent target organ for such cell-based therapeutics due to its ready accessibility, the prevalence of vasculo- and neurodegenerative diseases affecting vision, and the availability of animal models to ...

Stemness, cancer, and cancer stem cells [PDF]
Cell Cycle, 2008 The ability of cancers to grow indefinitely has fueled the idea that cancer and stem cells may have common underlying mechanisms. Detailed gene expression maps have now shown the diversity and distinctiveness in gene expression programs associated with stemness in embryonic and adult stem cells. These maps have further revealed a shared transcriptional

Science, 2007 Two converging events took place on 9 August that ought to have the scientific community scratching its collective head. One of these is an anniversary: On that date in 2001, President George W. Bush signed an Executive Order banning any use of federal funds to support research on stem cells (save, of course, for those 78 preexisting cell lines, only ...

To STEM or not to STEM? That is not the question
Cypriot Journal of Educational Sciences, 2018 The aim of this study is to identify the faults in Science, Technology, Engineering and Mathematics (STEM) education and to provide an approach to how these deficiencies can be eliminated. The STEM approach can provide students with an interdisciplinary point of view to gain creativity, critical thinking, high-level skills of thinking and problem ...

Hematopoietic stem cell metabolism and stemness
Blood Science, 2019 AbstractHematopoietic stem cells (HSCs) are considered to originate from the aorta-gonad-mesonephros, migrate into fetal liver for a rapid expansion, and eventually reside into a unique hypoxic bone marrow niche, where they maintain their homeostasis throughout their life span.

Consonant gradation in Fula suffixes the ugly truth
Studies in African Linguistics, 1988 In this paper, I will argue that Skousen's account of the differences between stems and suffixes requires substantial revision and elaboration. I will argue further that the complexities of the behavior of suffixes preclude the possibility of providing ...

Effect of two seeding rates on yield and yield components of winter and spring faba bean
Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2022 In Central European cropping systems, there is increasing interest in winter faba bean (Vicia faba L. minor), which is traditionally used as a spring crop. But limited knowledge on yield and yield formation and optimum seeding rate exist.

Influence of Pyrolysis Temperature on Biochar Produced from Lignin–Rich Biorefinery Residue
ChemEngineering, 2022 The biorefinery concept is growing rapidly for bio-based production of fuels and products, and steam explosion is by far the most applied pre-treatment technology allowing the delignification of lignocellulosic biomass.
