When the stem cells inside start growing out onto the underlying feeder cells, the researchers don't try to hurry the process. Most scientists working with embryos left over from in-vitro-fertilization treatments will use chemicals at this stage to separate the cells. "I think the less we manipulate the cells the better," Hwang says...
...technically legal in almost every state. Only South Dakota bans it altogether, and most states simply have no relevant legislation. Seven states restrict research--including Michigan, which prohibits it on live embryos, making any cutting-edge work all but impossible, and Louisiana, which specifically protects embryos created by in vitro fertilization. A handful of states, including Pennsylvania and Nebraska, do not allow public funding...
...held a Palm Sunday session so that it could deliver a lifeline to Terri Schiavo--is expected to consider legislation that could dramatically expand the number of stem-cell "lines" available to federally funded research by making accessible tens of thousands of embryos that have been created through in vitro fertilization. The bill contains a number of safeguards aimed at ensuring that it would apply only to embryos that would otherwise have been discarded. It stipulates that the embryos must have been created by individuals seeking fertility treatment and who then discovered that they had produced "in excess...
...human embryo should be grown in a lab more than 14 days--when the first primitive streak of a nervous system appears. (This is already common practice for in-vitro-fertilization labs...
Both State House and Senate versions of the bill allow for the use of embryonic stem cells obtained from in vitro fertilization (IVF) clinics and a cloning process called somatic cell nuclear transfer...
