Could humans ever regenerate the heart? The answer is YES.

 

Nowadays, there are a lot of people who need the organs immediately, but there are not that many supplies of organs to fulfill their needs in order to save their life. However, recently, the scientists figured out that the answer for whether it is possible to regenerate the organs turned out to be YES. In a new study published in the journal Proceedings of the National Academy of Sciences, the University of Florida scientist and colleagues found genes known to form hearts cells in humans and other animals in the gut of a muscle-less and heartless sea anemone. However, this is not just a simple, ordinary creature. It has very unique superpower-like abilities, which is it can be cut into many pieces and each piece will regenerate into a new animal. They figured out that this is very useful because they can modify the genes in this sea anemone and cut it into tiny pieces, then it’s population will automatically increase and it would make a new animal.

But how does it work? Usually, in humans, it doesn’t work. If we take the skin off and try to regenerate into the heart, it is impossible to do it. The reason why it is impossible is that we do have ‘lock down loops’. This is the thing when the genes are turned on once, they tell each other to stay on in an animal’s cells for its entire lifetime. In other words, animals with a lock-down such as vertebrates and flies on their genes cannot grow new heart parts or use those cells for other functions. Thus our skin cell can only produce skin cell.

On the other hand, apparently, in sea anemone embryos, the lock-down loops do not exist. Which means one cell can easily change to other cells and be part of it naturally. Scientists can easily modify the genes and make it into a heart, which can save one’s lives. Moreover, according to the website, the study supports the idea that definitive muscle cells found in the majority of animals arose from a bifunctional gut tissue, that had both absorptive and contractile properties. And, in the sea anemone tissue, it has characteristics of the heart cells which is rhythmic peristaltic waves of contraction. Thus, this might be the key to produce not the artificial organs, but the real organs made from the animal.
