There it goes....another news from the stem cells breakthrough. Scientific progress is indeed moving forward faster than anytime in human history.
From the New York Times, as reported by The Associated Press:
Scientists for the first time have grown human heart valves using stem cells from the fluid that cushions babies in the womb, offering an approach that may be used to repair defective hearts.
The Swiss experiment follows recent successes at growing bladders and blood vessels and suggests that people may one day be able to grow their own replacement heart parts, in some cases, even before they are born.
It is one of several tissue engineering advances that could lead to homegrown heart valves that are more durable and effective than artificial or cadaver valves.
