Scientists are discovering the secrets behind whole-body DNA regeneration

A team at Harvard has released a study on panther worms which revealed a regenerative master switch called early growth response, or EGR.

Scientists want to know why some fauna, like some species of the humble jellyfish, can regenerate their whole bodies following an injury. In a paper published last Friday, a team at Harvard have made some breakthroughs.

With three-banded panther worms as their test subjects, Harvard’s Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava and her team discovered a master control gene that’s activated by noncoding DNA, according to the Harvard Gazette.

Harvard University uncovers DNA switch that controls genes for whole-body regeneration

A piece of non-coding DNA may hold the key to how humans could regenerate body parts

Humans may one day have the ability to regrow limbs after scientists at Harvard University uncovered the DNA switch that controls genes for whole-body regeneration.

Some animals can achieve extraordinary feats of repair, such as salamanders which grow back legs, or geckos which can shed their tails to escape predators and then form new ones in just two months.

Planarian worms, jellyfish, and sea anemones go even further, actually regenerating their entire bodies after being cut in half.

Now scientists have discovered that that in worms, a section of non-coding or ‘junk’ DNA controls the activation of a ‘master control gene’ called early growth response (EGR) which acts like a power switch, turning regeneration on or off.

Self-healing plastic grows back after damage

self-healing plastic

The newly-developed self-healing plastic can take rather extensive damage and heal it through a process of regeneration.

There are several self-healing substances in the world, ranging from the LG G Flex’s scratch-healing casing to Stanford’s synthetic self-healing skin.  A plastic developed by the University of Illinois is one of the latest plastics developed that regenerates when damaged.

3D printing body parts will revolutionize medicine

Printing kidneys.

3-D printing has grown over the past two decades from a niche manufacturing process to a $2.7-billion industry, responsible for the fabrication of all sorts of things: toys, wristwatches, airplane parts, food. Now scientists are working to apply similar 3-D–printing technology to the field of medicine, accelerating an equally dramatic change. But it’s much different, and much easier, to print with plastic, metal, or chocolate than to print with living cells.

Salamander: superhero of regeneration

 The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord — even bits of lopped-off brain. But it turns out that remarkable ability isn’t so mysterious after all — suggesting that researchers could learn how to replicate it in people.

Study Shows The Human Heart Can Grow New Cells

Study Shows The Human Heart Can Grow New Cells

Heart muscle cells can be grown from human embryonic stem cells, but new research suggests the adult heart can grow new cells, too. 
 

The human heart has a notorious reputation for being unable to heal itself, but new research suggests it is capable of at least some self-repair. Using carbon dating to gauge the age of heart cells, scientists have found that low numbers of new heart cells are continuously being created throughout a person’s life. This raises the possibility that we may one day be able to use drugs to directly stimulate this regenerative capacity to patch up damaged hearts, rather than relying on cell-transplantation therapies.

Injectable Bone Repairs Broken Bones In Minutes

Injectable Bone Repairs Broken Bones In Minutes 

The worst part of breaking a bone (besides the pain) is the healing process. Wearing an uncomfortable cast can be irritating and aggravating, making it harder to move around for months at a time. Well, that process may soon change. A company has developed a product called “Injectable Bone” that may repair the broken bone in minutes.

New Tissue Regeneration Technique Is An Alternative For Coronary Bypass Surgery

New Tissue Regeneration Technique Is An Alternative For Coronary Bypass Surgery 

An Israeli team of cardiologists at the Carmel Medical Center in Haifa, has created an alternative for coronary bypass surgery, by developing a tissue regeneration technique that enables the body to produce new blood vessels. This development signifies a a major breakthrough in the field of artery bypass and may eliminate the need for bypass surgeries in the future.

Researchers Regrow Cells OF The Inner Retina

Researchers Regrow Cells OF The Inner Retina 

Cells in the retina of mice can be coaxed to create new neurons following an injury, according to new research from the University of Washington. This is the most definitive demonstration to date that such regeneration is possible, given the right cues, for a specific type of neuron in the inner retina of a mammal.
