Scientists found that the gene can heal itself

Deep in our bodies, there are many types of genes that are 'switched on and off' for many years, including those that can help the body grow to the 'upper' position. This is the reason for scientists to search for 'magic code' that can help us reborn bodies or make our hands regrow if unfortunately broken. A Harvard University researcher believes he seems to have found it.

George Daley from Harvard Medical School accidentally discovered an interesting thing. While conducting the identification technique for mice in his lab - by cutting ears or the tips of his toes - he noticed some strange phenomena. Unlike other animals, these small mice may develop their ears and toes again for a few days. The reason is because they have been genetically engineered so that a gene that helps them grow in the womb could continue to function as soon as the mouse was born. In other words, this gene will never turn itself off. Researchers call this gene Lin28a , and by promoting metabolism, it can deceive the body that it is younger than it really is.

This is really good news. However, the question is: How good? Daley and his company claim that this gene can regenerate parts of the body, but this method is still limited. The American scientist described the following:

'The power of Lin28a gene appears only within a limited time. When mice were larger - about 5 weeks old - scientists could not replicate their legs, even if the gene was stimulated. And the mouse with the activated Lin28a gene cannot repair the heart damage itself, probably because the protein is not homogenous in all areas of the body. "

So Lin28a is still active - but not forever and not all parts of the body. However, there are many other types of genes in the body that may be more important than Lin28a. Now scientists know that the body's healing process can be controlled by metabolic activities, and they will be able to find other related genes. In other words, learn where to find them.

Obviously self-regeneration is still quite far away, but this is also a significant step forward. And with new findings about Lin28a, it also plays an important role in finding new drugs that can help the body recover faster and better after injury.
