Yes, and you're right, I overlooked that part.
How about "Endothelial cells derived from human embryonic stem cells form durable blood vessels in vivo"?

I am assuming that you did not actually read the article. This kind of publication is known as a “brief communication”, which means that while the results being reported are very exciting, they are preliminary. For example, there is no information whether any of the mice developed cancers.
Interestingly, Dr. Scadden, who was the senior author on this publication (the web site you referenced messed up the order of the authors), had a Newsweek article where he is very upbeat about the potential of induced pluripotent stem cells (iPS), which are a type of adult stem cell.
