Scientists create world's first 3D printed beating heart muscles and tissues.
Heart muscles that actually beat, created artificially in the lab, have for the
first time become a reality.
In a major breakthrough that could repair millions of human hearts damaged after massive heart attack, scientists have for the first time successfully implanted artificial heart tissues that actually beat in animals. When a heart gets damaged during a major heart attack, the result can be deadly.
But scientists working on a way to repair the vital organ have now engineered tissue that closely mimics natural heart muscle that beats, not only in a lab dish but also when implanted into animals.
"Repairing damaged hearts could help millions of people around the world live longer, healthier lives"
The researchers calculated that the difference between the highest and lowest levels of physical activity would translate into an estimated 11 per cent lower risk of heart attack or sudden cardiac death.
