Christine Dell’ Amore in her article, “Heart Cells Can Regenerate, Nuclear-Bomb Evidence Shows” argues that our heart cells are replaced over our lifetimes. She further insinuates that the discovery might lead to new heart treatments such as new drugs or other medical treatments that can increase heart cell growth in people with heart trouble. The tissue sampled from people born up to 22 years before the onset on the 1950s nuclear tests showed that some heart cells had higher carbon-14 concentrations, suggesting that the cells had been created many years after their birth. Dell’ Amore expresses how this new discovery can lead to many new treatments such as stem cell treatments.
Discussion Questions:
Clarification: How accurate is the nuclear-bomb evidence and how does it confirm that heart cells can be regenerated?
Application: How can this discovery help create new medical treatments?
