Protein is Key to Embryonic Stem Cell Differentiation
Investigators at Burnham Institute for Medical Research (Burnham) have learned that a protein called Shp2 plays a critical role in the pathways that control decisions for differentiation or self-renewal in both human embryonic stem cells (hESCs) and mouse embryonic stem cells (mESCs). view more (2009-03-19)
Stem cells provide new tool for studying disease and identifying ALS drugs
Results of two studies funded by Project A.L.S. and appearing in today's advance online publication of Nature Neuroscience demonstrate that embryonic stem cells may provide a new tool for studying disease mechanisms and for identifying drugs to slow ALS, also known as Lou Gehrig's disease. view more (2007-04-17)
Molecular 'marker' on stem cells aids research, perhaps therapies
A sugar molecule present on embryonic stem cells also has been found on the surface of a type of adult stem cell, a discovery that may help researchers isolate and purify adult stem cells for use in therapies aimed at bone healing, tendon repair and cartilage regeneration, researchers at UT Southwestern Medical Center report. view more (2006-12-04)
Center releases new public survey on stem cells
Stem cells are unique among human cells in that they possess the uncanny ability to develop into virtually any other cell of the body, offering a hypothetical tool kit for repairing diseased hearts, mending broken spinal cords, or correcting genetic diseases, among other hoped-for benefits. view more (2005-10-14)
Stem-cell transplantation improves muscles in MD animal model, UT Southwestern researchers report
Using embryonic stem cells from mice, UT Southwestern Medical Center researchers have prompted the growth of healthy - and more importantly, functioning - muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy. view more (2008-01-21)
Don't ban embryo-based research says new chairman of European fertility organisation
The incoming chairman of an organisation representing over 4,000 international fertility experts has urged the EU not to go down the road of attempting to ban research on embryonic stem cells. Professor Arne Sunde, who takes over tomorrow as chairman of the European Society of Human Reproduction and Embryology, told a news briefing today (Monday... view more... (2003-06-27)
Engineered pig stem cells bridge the mouse-human gap
The discovery that adult skin cells can be 'reprogrammed' to behave like stem cells has been a major scientific boon, providing a way to tap the potential of embryonic stem cells without the associated ethical quandaries. view more (2009-06-04)
New strategy for mending broken hearts?
By mimicking the way embryonic stem cells develop into heart muscle in a lab, Duke University bioengineers believe they have taken an important first step toward growing a living "heart patch" to repair heart tissue damaged by disease. view more (2009-10-12)
Malignant melanoma cells secrete protein required for embryo formation
A Northwestern University research group has discovered that aggressive melanoma cells secrete Nodal, a protein that is critical to proper embryo formation. view more (2006-07-31)
Carnegie Mellon scientist plays key role in unveiling sea urchin genome
Carnegie Mellon University has played a key role in an international, multi-institutional collaboration to sequence the sea urchin genome. view more (2006-11-13)
Origin of cells for connective tissues of skull and face challenged
With improved resolution, tissue-specific molecular markers and precise timing, University of Oregon biologist James A. Weston and colleagues have possibly overturned a long-standing assumption about the origin of embryonic cells that give rise to connective and skeletal tissues that form the base of the skull and facial structures in back-boned... view more...

Medium is the message for stem cells in search of identities
Embryonic stem cells, prized for their astonishing ability to apparently transform into any kind of cell in the body, acquire their identities in part by interacting with their surroundings—even when they are outside of the body in a laboratory dish, University of Florida scientists report. view more (2006-07-06)
Ground rules for Finnish research on embryos and stem cells
Finnish researchers held a discussion forum on embryonic and stem cell research in November 2001. The researchers surveyed the use of embryos and stem cells in Finnish research and discussed the goals, fields of emphasis and ethical principles of this research in Finland. More than 140 researchers and other players from. e.g. universities,... view more... (2002-02-20)
Scientists use stem cells to grow cartilage
Scientists from Imperial College London have successfully converted human embryonic stem cells into cartilage cells, offering encouragement that replacement cartilage could one day be grown for transplantation. view more (2005-11-17)
Standards in stem cell research
Standards in stem cell research help both scientists and regulators to manage uncertainty and the unknown, according to new research funded by the Economic and Social Research Council. view more (2008-07-21)
Stem cell regeneration repairs congenital heart defect
Mayo Clinic investigators have demonstrated that stem cells can be used to regenerate heart tissue to treat dilated cardiomyopathy, a congenital defect. view more (2008-09-12)
Study: Donated embryos could result in more than 2,000 new embryonic stem cell lines
In a survey of more than one thousand infertility patients with frozen embryos, 60 percent of patients report that they are likely to donate their embryos to stem cell research. view more (2007-06-21)
Gene key to taste bud development identified
The gene, SOX2, stimulates stem cells on the surface of the embryonic tongue and in the back of the mouth to transform into taste buds, according to the researchers. view more (2006-10-02)
Scientists show gene mutation may cause immature lungs in newborns
Scientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing. view more (2008-11-25)
Sign of 'Embryonic Planets' Forming in Nearby Stellar Systems
Astronomers at the University of Rochester are pointing to three nearby stars they say may hold "embryonic planets"-a missing link in planet-formation theories. view more (2007-10-02)
