Zebra fish also have the ability to regenerate heart tissue, so another experiment was done involving the zebra fish. In this study, they blocked the gene expression of the Irrc10 gene and the zebra fish were no longer able to regenerate their heart tissue. This shows that this gene is responsible for the ability to regenerate the tissue.
In future studies, the researchers would like to study the mechanisms of how these fish regenerate and heal their hearts with the help of the gene, in order to find a way that humans could do it too. This could solve many problems for humans with the heart failure condition. Since heart failure causes damage to the muscle and cells of the heart, regeneration would be a much more efficient solution than heart transplants. Many people die from heart failure, but this information has the potential to save the lives of people with the condition in the future. This is an amazing discovery that could lead to a huge breakthrough for humans.

It would be amazing to find a way to regenerate a damaged heart. This breakthrough would have so many uses and could literally give people a new life. However, would it be an ethical challenge to enhance the human heart so it could regenerate? What about if an endurance athlete genuinely gets these new supplements or surgery, would that disqualify them from racing now that the heart could be potentially stronger? Personally, I would be curious to know how the ability to regenerate a damaged heart affects society. The philosophy from Thomas Malthus was that people do not overpopulate because of war, famine and disease, but with the ability to heal a heart, people could live drastically longer, for better and worse.
