To perform the procedure, the researchers first took about 10 grams of muscle from one of the patient’s thighs. Myoblast cells (a type of muscle stem cell) were then extracted from the muscle tissue, placed in a culture solution and grown into 50-micron-thick sheets measuring about 5 centimeters (2 inches) in diameter. Several layers of myoblast sheets were then applied to the surface of the impaired heart, where they helped strengthen the muscle and restore cardiac function.

I’m really impressed by Japanese researchers. If there’s a chance, I shall do my research in Japan.
