Scientists Identify DNA That Could Lead to Humans Regrowing Limbs

Scientists at Harvard University claim they have identified the mechanism that allows the three-banded panther worm to regenerate any body part within a matter of days. The gene, referred to as the early growth response or EGR, activates a complex system of genetic code that makes regeneration possible. Humans also possess this gene, which leaves scientists hopeful that humans will one day be able to regrow missing limbs and body parts.

There are about 2.1 million people currently living with limb loss in the United States and 185,000 who undergo amputations each year. Scientists are hopeful that this discovery could help millions across the globe in life-changing ways. See how this gene works in humans...

How Some Species Regenerate Lost Body Parts

For centuries, man has witnessed the remarkable miracle of regeneration in nature. Many species, including salamanders, starfish, sponges, insects and worms, can easily regrow missing body parts. Some can even create another complete copy of themselves using severed body parts. For example, a starfish that loses a leg can regrow the missing leg and use the severed leg to grow an entire starfish body, thus creating two identical starfish.

Scientists have been researching the power of regeneration and have found vast variances among species, which means that regeneration is extremely complex. However, they believe that the key stem cell processes involved, although ancient, are similar to each other and are still present in most species, including humans.

The DNA Switch That Makes Regeneration Possible

Scientists at Harvard University have discovered the primary gene that switches on the process of regeneration in organisms that have the power. This master gene, called the EGR, activates a complex genetic code that makes regeneration possible. It triggers no less than 18,000 genome regions that undergo physical transformation during the process.

The importance of the gene is indisputable. When scientists inhibited the gene’s activity, tissue regeneration was not possible.

Humans Possess the Regeneration Master Control Gene

Humans do possess the EGR gene, and it works! Unfortunately, it doesn’t work in humans quite like it does in less complex species. In humans, the gene works at the cellular level, regrowing and replacing damaged cells. You can see its power in your skin, which replaces itself constantly, and in your body’s ability to heal itself.

While human limb regeneration might still be a long way off, scientists are hopeful that one day they’ll be able to use the EGR switch to stimulate more complex growth in humans. You never know --- we may just one day have the ability to regrow body parts.
