From Voice of America, an look into the current state of first generation adult stem cell therapies for heart disease: "Three months after the injections, more than 100 patients saw significant improvement in blood flow to the heart and the heart muscle worked twice as well as before the treatment. ... You can see where the blood vessel is blocked. You can see the blood flowing and then it just stops. Now, three months later, after injection of stem cells in that area, you can see that there's a new vessel bringing the blood down. ... Researchers say when it comes to building blood vessels, using your own cells could become a common treatment within a few years - very good news for the millions of people who suffer from heart disease."
