A biotechnology company has developed a new way of creating stem cells without destroying human embryos, billing it as a potential solution to a contentious political and ethical debate.

Scientists have developed an easy-to-use technique for reprogramming a skin cell of a mouse back to the embryonic state, which could have implications for regenerative medicine in humans.

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.

A measure that forbids cloning human embryos but allows scientists to extract stem cells from unwanted embryos for medical research is approved by Swiss voters. The restrictive legislation is similar to that of the Netherlands and Spain.

A technique would let scientists use a patientâs skin cell to generate new heart, liver or kidney cells that might be transplantable.

By putting off a vote on banning all human cloning, nations have let embryo research for therapeutic reasons gain momentum. By Gregory M. Lamb | Staff writer of The Christian Science Monitor.

A new way to manipulate human embryonic stem cells offers hope of a treatment for muscular dystrophies.

Embryonic stem cells may not have to actually grow replacement body parts to be useful. New research suggests these cells also secrete healing molecules powerful enough to reverse a lethal birth defect in mice.

Scientists working to build a life form from scratch have patented the method they plan to use.

Human therapeutic cloning has moved a  step closer after U.S. researchers said they had successfully  created embryonic stem cells from monkey embryos.

Scientists in Massachusetts said yesterday that they had created several colonies of human embryonic stem cells without harming the embryos from which they were derived, the latest in a series of advances that could speed development of stem-cell-based treatments for a variety of diseases.

A treatment that involves slipping billions of copies of a gene into the brain seemed to improve symptoms without causing side effects.

Researchers came a step closer to finding a safe way to use stem cells in clinical treatment Thursday when a team of Japanese scientists announced they found a way to induce stem cells without triggering tumors.

Cloning sperm could enable men with very low sperm counts to become fathers, say US scientists.

In a big step toward a long-sought goal, three teams of scientists say they've produced the equivalent of embryonic stem cells, at least in mice, without taking the controversial step of destroying embryos.

Scientists said yesterday they had transplanted a microbe's entire, tangled mass of DNA into a closely related organism, a delicate operation that cleanly transformed the recipient from one species into the other.
