Positive side effect of nuclear bomb experiments - evidence of heart cells regeneration

Recent discovery shows that the human heart cells can regenerate over the course of the lifetime. The tests were done employing human cells irradiated during the 1950’s nuclear tests. It’s been found that the cells that control the heart muscle contractions leading to blood pumping through the body, could regenerate at a rate of 1% per year when aged 25 and decreasing down to 0.4 % at the age of 75.
Carbon 14 radioactive isotope peak detection.
The experiments were based on the spectrometric technique by measuring the radioactive isotope of carbon 14 whose concentration increased during the nuclear tests and led to contamination of anyone alive at that time. The outcome revealed that part of cells had a higher concentration of carbon suggesting that the respective cells regenerate themselves.
The discovery is considered a step forward for developing new medication that might help the growth of the cells in humans experiencing heart problems. The usual treatment consists of taking cells from other organs and introducing them into the heart.
The experiments were carried out by swedish researchers and the results published in Science, Vol. 324, April 3, 2009.
