Cells grown in culture are not alone: They are constantly communicating with one another by sending signals through their culture media that are picked up and transmitted by other cells in the media. When thousands of cells are cultured together in a dish, there are hundreds of thousands of these signals present every minute, all competing to be heard.
Scientists trying to direct cells to do useful things — like causing stem cells to turn into neurons or heart cells — typically try to overcome these signals by adding their own exogenous factors. These exogenous factors are often added at

On May 6, France’s Council of State (the highest administrative court and legal advisor to the executive branch) declared that it was against the practice of “renting out one’s uterus” and in favor of the permanent authorization regulations for embryo research and embryonic stem cell research under certain conditions. French Prime Minister Francois Fillon had asked the court for its opinion, in a reexamination of a 2004 bioethics law.
-Considering the interest of the child and the mother carrying the child and basic underlying principles of the present ban, we hereby recommend to not legalize
OKLAHOMA CITY — The debate over stem cell research stirs up deeply held religious, moral and ethical views.
But some aren’t sure what a possible ban or veto will mean for Oklahoma.
Cells tinier than a pin head have some asking larger-than-life questions.
House Bill 1326 would criminalize research that would destroy or cause substantial risk to a human embryo.
The Oklahoma Medical Research Foundation reports this type of research isn’t even happening in the state right now.
The foundation is doing research on adult stem cells but not embryonic.
But its workers say no one knows what the medical landscape will look like in

Human embryonic stem cells implanted into mice specifically engineered to have a serious retinal dysfunction resulting in blindness have restored the animal’s capacity to sense light during tests.
The results, published in international magazine, Cell Stem Cell, were obtained in the United States by a research group in the Department of Biological Structure at the University of Washington in Seattle. The study, performed by Deepak Lamba, Juliane Gust, and Thomas Reh, demonstrated that it is possible to obtain retina progenitor cells from stem cells derived from the embryo. The researchers observed, “In principle, embryonic stem

Korean scientists are moving closer to cloning embryonic stem cells, the unprecedented breakthrough that their compatriot and disgraced scientist Hwang Woo-suk claimed to have achieved in 2004, only to have this disproved later.
Currently, a team at the Cha Medical Center is working on a project after getting state approval last year, while another team headed by professor Park Se-pill at Jeju National University is also set to begin research.
Park and his associates are awaiting final approval from the National Bioethics Committee.
“If the endorsement is made before June, we should be able to clone human embryonic stem cells
