Human embryonic stem cells remain embryonic because of epigenetic factors
A human embryonic stem cell is reined in - prevented from giving up its unique characteristics of self-renewal and pluripotency - by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue. view more (2007-10-05)
Forsyth scientists gain new understanding of adult stem cell regulation
Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells. Research with the flatworm, planaria, found a novel role for the proteins involved in cell-to-cell communication. view more (2007-08-01)
Heart stem cell scientist to honor pioneering woman scientist in keynote speech
Professor Christine Mummery, one of the world's leading heart stem cell experts, will later today (9 April) honour the memory of Dame Anne McLaren in the keynote lecture of the inaugural UK National Stem Cell Network Science Meeting in Edinburgh. view more (2008-04-10)
Detailed 3-D image catches a key regulator of neural stem cell differentiation in action
Researchers at the Salk Institute for Biological Studies in collaboration with scientists at the University of California, San Diego (UCSD) took a high resolution "action shot" of a protein switch that plays a crucial role in the development of the nervous system. view more (2006-12-08)
Discarded placentas deliver researchers promising cells similar to embryonic stem cells
Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells. view more (2005-08-08)
Liver Cancer Linked to Cellular Repair Pathway
The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer. view more (2006-03-30)
Technique enables efficient gene splicing in human embryonic stem cells
A novel technique allows researchers to efficiently and precisely modify or introduce genes into the genomes of human embryonic stem cells (ESCs) and induced pluripotent stem (iPS) cells, according to Whitehead scientists. view more (2009-08-14)
Sperm stem cells closer to being like embryonic stem cells
New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. view more (2005-11-16)
Scientists find potential stem cells in amniotic fluid - a new source?
Research by Austrian geneticists has raised the possibility that stem cells[1] could be isolated from amniotic fluid - the protective 'bath water' that surrounds the unborn baby. Geneticist Professor Markus Hengstschl'¤ger and his team at the University of Vienna have isolated a subgroup of cells from amniotic fluid that express a protein called... view more... (2003-06-27)
Male germ cells can be directly converted into other cell types
Researchers have found a way to directly convert spermatogonial stem cells, the precursors of sperm cells, into tissues of the prostate, skin and uterus. view more (2009-07-29)
Fossilised Embryos - 500 Million Years Old
Evidence from fossilised embryos of worm-like creatures that lived 500 million years ago shows that embryos developed then in much the same way as their living relatives do today. The implications of this remarkable discovery, reported in this week's issue of Nature, is that embryological processes that occur today must have been established very... view more... (2004-01-12)
UC Riverside researcher develops novel method to grow human embryonic stem cells
The majority of researchers working with human embryonic stem cells (hESCs) - cells which produce any type of specialized adult cells in the human body - use animal-based materials for culturing the cells. But because these materials are animal-based, they could transmit viruses and other pathogens to the hESCs, making the cells unsuitable for... view more... (2008-08-20)
75 million SEK for Swedish stem cell research
Swedish stem cell research is to receive a supplement of 75 million SEK over five years. The Juvenile Diabetes Research Foundation International (JDRF), the world’s leading nonprofit, nongovernmental funder of diabetes research will contribute with 50 million SEK. The Swedish Research Council contributes with 20 million and the Swedish... view more... (2002-03-21)
Study reveals a key to blood vessel growth and possible drug target
Researchers have identified a molecular pathway that plays a critical role in the growth of blood vessels. The finding not only offers an important insight into the development of the vascular system during embryonic development but suggests a potential target for inhibiting the blood vessels that fuel cancers, diabetic eye complications and... view more...

U-M team identifies gene that regulates blood-forming fetal stem cells
In the rancorous public debate over federal research funding, stem cells are generally assigned to one of two categories: embryonic or adult. view more (2007-07-27)
Human embryonic stem cells developed from 4-cell embryo; world first may lessen ethical concerns
For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo. view more (2008-07-09)
Markers of brain cell development may help success of stem cell transplants
Four sugar-coated faces made by stem cells as they differentiate into brain cells during development have been identified by scientists. view more (2005-09-07)
Embryo fossils reveal animal complexity 10 million years before Cambrian Explosion
Fossilized embryos predating the Cambrian Explosion by 10 million years provide evidence that early animals had already begun to adopt some of the structures and processes seen in today's embryos, say researchers from Indiana University Bloomington and nine other institutions in this week's Science. view more (2006-10-13)
Memory mission explores new territory in neuroscience
Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home. view more (2008-11-21)
Genetic tug of war determines sexual differentiation
Whether or not a fertilized mammalian egg ultimately develops into a male or female is determined by the winner of a tug of war between two different genes encoding signaling proteins and the divergent pathways they control. view more (2006-05-24)
