Generates blood vessels from stem cells

Artificial blood vessels created by American scientists can exist in humans for up to 9 months.

Rakesh Jain, a Massachusetts General Hospital doctor in the United States, and colleagues transplant stem cells to the brain surface of mice. After two weeks, stem cells develop into blood vessels. Some of them exist for up to 280 days, Telegraph reported.

Some researchers have used similar methods to create blood vessels from stem cells, but they implant stem cells under the skin of animals, not implant on the surface of the brain. So their blood vessels only exist for a short time. In addition, their method causes the time of stem cells to turn into blood vessels five times longer than Jain's method.

"Our team has created an effective method to create blood vessels from stem cells in mice , " Jain said.

The creation of blood vessels from stem cells can lead to new therapies for some diseases such as diabetes and heart disease.

Stem cells (or germ cells) exist only in adult and fetal bodies. They are capable of turning into all types of tissue, thus acting as a "repair kit" in the body to replace tissue, dead or too old cells.
