The results were striking. Not only did scar tissue retreat -- shrinking 40% in Ken Milles, and between 30% and 47% in other test subjects -- but the patients actually generated new heart tissue. On average, the stem cell recipients grew the equivalent of 600 million new heart cells, according to Marban, who used MRI imaging to measure changes. By way of perspective, a major heart attack might kill off a billion cells.10 "This is unprecedented, the first time anyone has grown living heart muscle," says Marban. "No one else has demonstrated that. It's very gratifying, especially when the conventional teaching has been that the damage is irreversible."11 Perhaps even more important, no treated patient in either study suffered a significant health setback.12 The twin findings are a boost to the notion that the heart contains the seeds of its own rebirth. For years, doctors believed that heart cells, once destroyed, were gone forever. But in a series of experiments, researchers including Bolli's collaborator, Dr. Piero Anversa, found that the heart contains a type of stem cell that can develop into either heart muscle or blood vessel components -- in essence, whatever the heart requires at a particular point in time. The problem for patients like Mike Jones or Ken Milles is that there simply aren't enough of these repair cells waiting around. The experimental treatments involve removing stem cells through a biopsy and making millions of copies in a laboratory. i need help on Cornell Notes
