By using DNA samples from many hearts, the researchers estimated that a 4-year-old renews about 20% of heart muscle cells per year, and about 69 percent of the heart muscle cells of a 50-year-old were generated after he or she was born.
Usando mostras de ADN de moitos corazóns, estimaron que unha persoa de 20 anos renova aproximadamente o 1% das células do músculo cardíaco cada ano, e que aproximadamento o 45% das células musculares cardíacas das persoas de 50 anos se rexenerou desde o nacemento.
