The EMBO Journal, 2005 Stem cells are unique in their capacity to self-renew and generate differentiated progeny to maintain tissues throughout life. A common molecular program for stem cells has remained elusive. We discuss what the molecular logic of stemness may be. We suggest that it may not be coupled to distinct cellular properties such as self-renewal or multipotency,

Plastic and Reconstructive Surgery, 2010 Stem cells are self-renewing cells capable of differentiating into multiple cell lines and are classified according to their origin and their ability to differentiate. Enormous potential exists in use of stem cells for regenerative medicine. To produce effective stem cell-based treatments for a range of diseases, an improved understanding of stem cell ...

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 ...

Research interdisciplinarity: STEM versus non-STEM [PDF]
Scientometrics, 2020 Research collaboration among interdisciplinary teams has become a common trend in recent days. However, there is a lack of evidence in literature regarding which disciplines play dominant roles in interdisciplinary research settings. It is also unclear whether the dominant role of disciplines vary between STEM (Science, Technology, Engineering, and ...
