PHILADELPHIA (CBS) – Researchers at Massachusetts General Hospital have successfully made functional blood vessels from human stem cells in mouse models. Put in plain english, they developed blood vessels that can actually potentially work in a wide variety of situations.

The hope is that they could be used to replace clogged arteries – which give rise to heart attacks, strokes, and kidney disease. These vessels created from stem cells could become clog-free arteries and make a patient almost as good as new.

There ware numerous additional uses for these blood vessels. Prior to this work most blood vessels that were created were frail and easily torn limiting function.
