Researchers anticipate that adult and embryonic stem cells will soon be able to treat some of the world's most serious diseases. However, embryonic stem cells are still a controversial matter. An Israeli team has found a way to improve the production of new stem cells significantly.

For the first time in the world researchers at the Technion Institute of Technology and Rambam Medical Center in Haifa in Israel created new blood vessels using embryonic stem cells. The researchers are hoping to achieve effective treatment of heart disease in the future.
