This scientist re-wires frogs to grow extra limbs. Could it work in humans?

One morning in spring 2000, Michael Levin flopped in his chair and clicked on his desktop computer. A newly minted assistant professor at Harvard, Levin, then 30, was looking to solve a riddle that had baffled science for centuries: How do our dividing embryonic cells know on which side of our bodies to grow our hearts, our livers, our gall bladders? Countless people throughout history have been born with some, even all, of their organs transposed, and yet functioning. Levin suspected DNA alone was not to blame; there had to be some other trigger. Days earlier, he had ordered an imaging test on a half dozen chick embryos at the verge of organized development. As he pulled up the results, he stared, amazed. Electrical charges, rendered in yellows and reds, lay across the cells in patches, left to right, as clearly as a neon "This Way" arrow. Levin sat back and blinked. He was witnessing, for the first time in history, embryo cells telling each other left from right via electricity.

Humans and frogs are different creatures; that won't work efficiently. If you want to create monsters, that's a way I guess. Lol

[digaran]

Can I have an extra thingy or just an extra brain please? lolz.
One question, if everything is done by our brains like when I touch something my body sends signals to my brain and I feel it and the same feeling I am experiencing is registering as electricity moving in my brain, so how do I really feel? shouldn't brain sends something to me? oh wait all I feel and do is happening in my brain but am I my brain?
The person now is typing and sees and hears and feels, where is this person exactly? if when I touch my brain lights up and again upon feeling that touch my brain lights up and I feel it the same time.

If my brain is doing all the sending and receiving then where do I fit in here?

OMG

has science gone too far?

Is this mad as mad as a bog of frogs?

[Japan_peopleffs]

Perhaps in the distant future, it will work in humans, this process is too little studied. The idea is good, you need to develop in this direction.

[Drowzy]

This research needs grants! Just imagine, someone with a missing limb or even a missing organ can regrow it themselves simply by programming cells. So we are just computers made of bio matter instead of silicon. I always suspected that.

Too bad people who do research like this aren't allowed by the medical to use crowd funding.

[daronch]

Incredibly interesting and amazing at the same time. Definitely needs more funds and research. Many people will benefit from this.

[dawnasor]

That is very interesting but I dont think if that will work on human body.
Frogs and humans are different creature.Even they want to start a research on this their organization will against on it

[0xfff]

Okay. I search the article and I cannot find a picture of a frog with extra limbs. Please provide an image of a frog with extra limbs or delete thread because it is click bait. Thanks

[Eternu]

That would be interesting, but i think it is not possible. Frogs are so different from us humans, and that is where problem lies in. But lets think for a moment that it is possible. It would be interesting thing to have. Im not sure if it would affect regenerative power of healing, or just simple regrowing limbs or parts of human organs. If it would affect regenerative power of healing than people would be almost immortal. Next questions is, how fast could you grow new organ or limb xD . Its interesting topic yes, but impossible for now maybe.

[Seccerius]

A frog and a man are very different organisms. It would be very useful, but it's impossible for a person yet. In primitive and simpler beings, limbs are easier to regenerate. The human body is more complex and rejects all alien. Scientists are working in this direction, but so far there has been no tangible progress.

The process might be very complex to truly make work. But the start has been there ever since we have transplanted organs successfully.

This is really a very complicated process and not even all the transplanted organs take root, but this adds some life to some people. So far, only in the movies can sew the limbs of other people or grow new ones. I believe that someday people will be able to grow limbs.

[Qartada]

Frogs were seemingly just chosen to show that limb changes are possible, but it wouldn't work reasonably in humans.  Otherwise it would have happened in the past 17 years.

Yes. Animals have a different body structure and capabilities. For the human body it is necessary to do other technologies of growing limbs. The idea is very necessary and interesting, but medicine has so far advanced very little in this direction.

[dacueba]

you may rewire the body, but what about the brain?

the brain could not control extra legs

[00hash01]

It all depends on how the nerve endings grow there. The operations for sewing nerve endings are now very complex and have few lucky chances. If the limbs grow like nails, then the brain must control them without problems. But if they sew, that is the probability of non-appearance of a foreign body and the brain can not control them.

[Nathan047]

Could they? Probably, at least after some more research. Should they? NO. I think science goes to far once they start messing with genes and altering your body parts like that. At least that’s my opinion.

[Beans]

Frogs are very different from Humans. It could work in humans but it may take another give or take 30 years. Growing limbs on lab may take 30 years to be perfected but growing the limps directly from amputated person is much much longer I guess.

[DrVaribo]

Some animals can themselves regenerate torn limbs, but these are very simple organisms and they lack the immune system. The frog is a little more complicated, but compared to a man they are different. There were cases when young children could grow a lost finger, but I do not know how much this fact is true. We need to study this topic more and conduct research.

So does no one have a picture of the frog with extra limbs? I am very disappointed 

[BADecker]

You said it. Stop being disappointed in yourself. Do it.   

[Spirit2016]

I wonder what the Society for the Protection of Animals thinks about this. Is this action over the frog can be someone you need. Although maybe it matters to people in some sense.

I don't think Society for Protection of Animals would care much about me being interested in a picture. I think they would care more about the thousands of frogs that this scientist has probably killed when experimenting on them.

Experiments are important for people. If there were no experiments, for example, on frogs, then humanity would be very backward in the development of medicine. It is necessary to consider that these frogs made an important contribution to the development of the medical sphere and in the near future people will be able to grow limbs.

The French have long learned how to peacefully exist with frogs and benefit from it. They say that their meat is very tasty and healthy. But at the expense of growing a man's limbs, it seems to me from the realm of fantasy. A person's body grows all his life and time, it takes a lot.

Earlier organ transplantation was fantastic, but people have learned and are now successfully conducting such operations. If it was possible to grow limbs in a frog, then in a short time scientists will be able to grow limbs in humans.

[Sierra82fit]

I can not imagine that this experiment will help to grow people's feet. Assume the possibility of this action is also not possible, because the time of development of the frog's organism is much less than that of a person.

[Nathan047]

It might, think of it like experimenting on rats; they may be very different than people, but it allows scientists to begin experimentation until it is somewhat safe before they try on people (or more person like animals like monkeys or pigs).

Maybe in some far far future that could be possible. If you alter human gene and mix it with frogs or what ever animal you want, i know i would not like to be that "human" . I think that in that moment, if we take under consideration that it is possible, will would stop being humans as we know, we would evolve in totally new specie. But back to reality, its not possible, because if it was humans would evolve to that point till now.

[crwth]

There are a lot of animals that has that kind of ability that they can regrow parts of their body. Maybe scientists can reverse engineer and see how they could make it work with humans, probably against other animals first, not directly to human subjects.

[SkyNVS]

1000 years ago, people would laugh at you if you told them about anything we have today. Today, technology is growing faster than ever and its going to be possible soon enough.

Do you really think that thanks to this experiment, someone will manage to grow a man's legs? I think that this is complete nonsense and I do not think that this will be possible even with a huge leap in the development of medicine.

[BADecker]

I'm still waiting for scientists to take a detached frog leg, and grow a new frog onto the non-foot end of it.

This experiment might not be the answer, but I do think it will be possible one day.

[oxygen88]

Even if it could work one day, I still feel it is too scary on humans

[Nathan047]

Yea, I defiantly agree with you there; I don't think science should over be manipulating our bodys. The ONLY exception in my mind is when somebody has a medical condition/issue and science is manipulating his/her body to make it more normal.

I'm not surprised at all if manipulation with the human body begins. But it goes beyond understanding when genetics try to program a human child even at the embryo stage to see a particular child, sex, hair and skin color, and much more. This not normal.
