Scientists’ Work Could Clear Moral Hurdle to Embryonic Research

Scientists for the first time have turned ordinary skin cells into what appear to be embryonic stem cells — without having to use human eggs or make new human embryos in the process, as has always been required in the past, a Harvard research team announced yesterday.

New stem cell lines available


Researchers chafing under President Bush’s restrictions on human embryonic stem-cell research will have free access to 17 new cell lines provided by a team of academic scientists.

The First Human Cloned Embryo

November 24, 2001

Cloned early-stage human embryos and human embryos generated only from eggs, in a process called parthenogenesis now put therapeutic cloning within reach.

Subcommittee hears testimony on stem cell research


…..Among the witnesses were celebrities Mary Tyler Moore, who chairs the Juvenile Diabetes Foundation, and Michael J. Fox, who recently quit acting to focus on Parkinson’s disease research.

A Crucial Human Cell Isolated, Multiplied


Scientists announced yesterday they had achieved one of the most coveted goals in biology by isolating from human embryos and fetuses a primitive kind of cell that can grow into every kind of human tissue, including muscle, bone and brain.

Human Embryonic Stem Cells Found?

by J. Travis,

Biologists who ponder the remarkable process by which an embryo develops into an adult will long remember 1997. First came the cloning of Dolly the sheep. Now, investigators report they may have isolated for the first time human embryonic cells that have the potential to develop into muscle, blood, nerves, or any other tissue in the body.

“I feel fairly confident that they will be demonstrated to be totipotent,” says John D. Gearhart of Johns Hopkins Medical Institutions in Baltimore, who described the cells at last week’s International Congress of Developmental Biology in Snowbird, Utah.

With these mother cells, scientists may someday create many sorts of tissues to treat conditions such as spinal cord injuries, diabetes, leukemia, and even neurodegenerative disorders like Parkinson’s disease.
