Human stem cells capable of giving rise to any fetal or adult cell type are known as pluripotent stem cells. It is hoped that such cells, the most well known being human embryonic stem cells (hESCs), can be used to generate cell populations with therapeutic utility. In this context, neural derivatives of hESCs are being tested in clinical trials. However, Natalie Lefort and colleagues, at the Institute for Stem cell Therapy and Exploration of Monogenic diseases, France, have now generated...

Like fine chefs, scientists are seemingly approaching a day when they will be able to make nearly any type of tissue from human embryonic stem cells. You need nerves or pancreas, bone or skin? With the right combination of growth factors, skill and patience, a laboratory tissue culture dish promises to yield therapeutic wonders. But within these batches of newly generated cells lurks a big potential problem: Any remaining embryonic stem cells - those that haven't differentiated into the...

How is it that a disc-like cluster of cells transforms within the first month of pregnancy into an elongated embryo? This mechanism is a mystery that man has tried to unravel for millennia. The first significant step towards understanding the issue was made nearly a century ago in experiments conducted by the German embryologists Hans Spemann and Hilde Mangold. The two used early newt embryos and identified a group of cells within them which, upon transplantation, formed a two-headed...

BOSTON, July 7 /PRNewswire/ -- Two key focus areas of Biocell Center, the nation's first amniotic fluid stem cell bank, have been recently mentioned among the most important medical discoveries of the last century. Amniocentesis and non-embryonic stem cells were among the list of "Huge Medical Breakthroughs" presented in an article by Althea Chang on Mainstreet.com, produced by TheStreet.com on June 29, 2010. The story highlights some of the most important and influential breakthroughs...

Sperm cell precursors can be converted into other cell types, providing a possible alternative to the medical use of embryonic stem cells, U.S. researchers say. The University of Illinois research, described in the journal Stem Cells, improves on earlier research that showed that a kind of germ cell that leads to the production of sperm could eventually give rise to a few cells that looked and acted like embryonic stem cells. But the earlier process with the spermatagonial stem cells took...

Researchers are suggesting that discarded fallopian tubes from hysterectomies could be a good source of donor stem cells "” offering another "ethical" route to creating stem cell treatments without using embryos, BBC News reported. Experts say they contain a rich source of the immature cells that have the potential to become a variety of the body's tissues, like muscle and bone. Previous studies have shown it is possible to get mesenchymal stem cells from umbilical cords, menstrual...

PITTSBURGH -  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, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express. A part of the placenta called the amnion, or the outer membrane of the amniotic sac,...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Scientists looking for easier and less-controversial alternatives to stem cells from human embryos said on Friday they found a potential source in placentas saved during childbirth. They described primitive cells found in a part of the placenta called the amnion, which they coaxed into forming a variety of cell types and which look very similar to sought-after embryonic stem cells. With 4 million children born in the...
