Stem cells made from 'dead' human embryo
27492
Scientists say they have created a stem cell line from a human embryo that had stopped developing naturally, and so was considered dead. Using such embryos might ease ethical concerns about creating such cells, they suggested.

Voters in Switzerland have backed a new law permitting research on stem cells from human embryos. The Catholic Church and the influential Green Party had opposed the legislation, saying it involved taking human lives.

Biologists at the University of California, San Diego have found a fundamental mechanism used by embryonic stem cells to assure that genetically damaged stem cells do not divide and pass along the damage to daughter stem cells.

The prospect that âthe curseâ might be a source of stem cells to sustain life was a surprise to some experts.

Transplanting brain cells produced from human embryonic stem cells helped fix stroke damage in the brains of rats, according to scientists who hope to test the same thing in people within about five years.

NEW YORK -- Scientists say they've created embryonic stem cells by stimulating unfertilized eggs, a significant step toward producing transplant tissue that's genetically matched to women.

After years of searching, Shinya Yamanaka found a way to turn adult skin cells into the equivalent of human embryonic stem cells without using an actual embryo.

The discovery that it is possible to create equivalents to embryonic stem cells without destroying embryos has the potential to reshape -- and perhaps defuse -- the acrimonious political debate that has raged ever since human embryonic stem cells were discovered in 1998.

In a bid to sidestep the ethical debate over the use of human embryos in medical research, scientists have developed a way to derive viable stem cell lines without harming the embryo.

The human embryonic stem cells available for research are contaminated with nonhuman molecules from the culture medium used to grow the cells, researchers report.

Scientists have discovered a new type of  embryonic stem cell in mice and rats that should speed up  research into regenerative medicine and help in the hunt for  cures to a range of diseases.

Human egg cells can be tweaked to give rise to valued stem cells that match the tissue types of many different groups of people, U.S. and Russian researchers reported on Wednesday. They said the stem cells they have created from unfertilized human eggs look and act like embryonic stem cells.
