Scientists at the Massachusetts General Hospital and Harvard Medical School used adult skin cells to regenerate functional human heart tissue, bringing humanity one step closer the creating an artificial human.
The scientists took adult human stem cells, used a method called messenger RNA to turn them into pluripotent stem cells, and then turned them into two different types of cardiac cells.
For two weeks the researchers infused the hearts with a nutrient solution, which created the same circumstances a heart would grow inside a human body.
After that short amount of time, the scientists then shocked the heart with electricity, and it began beating.
This is the closest scientists have ever gotten to creating a beating human heart, and this brings scientists one step closer to the goal of developing a full artificial human by 2026.
