Anthony Atala: Growing new organs 

Nothing in recent memory has amazed me as much as this talk!

I'm very interested in your work Dr. Atala. Biomedical engineering at its finest.

he explains it so that everyone can understand it. great talk!

Yes, surgeons at Via Christi Hospital in Wichita Kansas gave my daughter Ambrotose and Osolean from company called Mannatech documented and her esophagus with stage 4 cancer grew back in eleven days. This discovery was made 20 years ago. Also, now they know that autistic children are missing massive amounts of N-glycans which is in the Ambrotose.

first good tedtalk ive seen in my life

I had heard about most of this through various articles, but having a talk like this summing up the state of the art in a field as fascinating as this is really... awesome.

Waitig to know the latest progress in this wonderful research.

That was one of the most incredible things I have ever seen. The future is exciting after all!

Why the hell didn't the audience applaud when they saw the heart valve, that's absolutely incredible!

Wow, his name is anthony and he looks a lot like the main actor from Monk. Also, this is fucking amazing. Please, more ted talks where the speaker has time to drive their points home.

Its 2016. NOTHING CHANGED.

this tedtalks thing is such a good idea. it exposes regular people to the cutting edge ideas of the future. normally would have to be there to here this, which means paying money and time, which most can't afford

I've read a couple of articles about growing organs but seing this...wow. If this goes to mass production 1)more people will have a chance to live longer and 2)the black market for organs will take an incredible hit.

I think this is the next step in organ transplants, and I know there is still a lot of work to be done and a lot of research still needs to be done, but the fact that this is actually happening. Also, Anthony talks about how it takes a very long time to get the formula right, but once this is complete then the work can be done. It just amazes me how far we have come in medicine and I think it's a good thing that we are taking steps this far forward. I have also heard that scientists are making progress on being able to grow human organs in other animals such as pigs. I think this is another great idea but you have to be able to insert human stem cells in to the pig and watch it grow. For some reason when I think about this it makes me kind of nervous because I can just imagine a pig walking around with a human leg or something. So when watching this video I was very happy with the progress being made but also humbled at the same time knowing how much time and research is being put into it to make it happen. Either way, I think we need to take steps like this when we have the technology and research available because if we don't then I feel as if its just going to waste.

Hope this tecnology grows so it can save lifes.

I am impressed beyond words and so thankful that this research is being done. Small question though has there been progress on connecting these organs to the nervous system as well?

Absolutely Phenomenal! God Bless any of you who are pursuing Medicine This will become your domain.

Im still waiting for my flying car promised 60 years ago.

wow. at 10:00 minutes, the engineered heart valve. that is absolutely mental! :) congratulations

Why are we, as a world, not pushing for improved medical technology? This stuff is incredible, and people like Atala are on the verge of some of the most fascinating and NECESSARY discoveries of the present.

Do a pubmed search on about endothelial cells, angiogenesis and growth factors. That will answer some of your queries.

I don't know if this guy had some presentation skills training, but he is great! He show wonderful things but I am curious how many of these will be widely used in 10 years.

You mean rapid prototype printers? You're not far off - afaik that's almost exactly how the simple organ printer in the video was working. It prints a single 2D layer, then the layer moves down, and it prints another 2D layer. All of the layers eventually form a 3D structure.

these people are the real doctors

This just blew my mind. I will be neat to see how this technology refines itself.

passion drives these kind of people!

Incredible yet still a long way to go.

this men is a hero.

And I was feeling all high and mighty because I grew some food in my back yard. These dudes are growing parts of humans.

This video is 7 years old at the time of writing and I know NOBODY and NO HOSPITAL that actually does that... it's fabulous but it DOESN'T EXIST OUTSIDE OF UNIVERSITIES AND TED TALKS AND SCIENCE JOURNALS! So as "fabulous" as it is, it is also WORTHLESS as long as it's not REAL IN THE REAL WORLD!

Really interesting, should give those critically injured people a second chance. I wonder if they could build and condition biological machines to do other things? Water pumps that use actual muscles and can heal punctures? Generators made of powerful organs that run on "food" and output biodegradable waste like we do? I guess they would need a heart as well. I know its off topic, or not possible, just what came to mind.

2:41 amazing spider man is unravelling before our very eyes

I would say no, because we have a build in mechanism that prohibits that. I am no biologist, but afaik it is the telomeres that are at the end of each chromosome, which get less and less with each cell reproduction, but they are essential for duplicating the chromosome, so there is a limit for our lifespan.

This is truly amazing I just can't see how, with great science like this going on, Britney Spears still ends up on the front page of newspapers, and this stuff goes virtually unreported.

Wow. This is huge!!!!! A big leap for health science.

Every day I love science more and more.

this is a good idea but only when no other alternative works. caution should be exercised.

I'm waiting for the regeneration of the thyroid gland.

Wow that printer concept is so interesting! They also have those 3D printers that create 3D models out of 3D graphics. I wonder if that is something that could be modified in the future to create full organs with all its components.

Yep, that's definitely him at 2:10.

Yet that's exactly what happens in transporters in startrek: - atomically copy original - send data - destroy original - atomically assemble new person. Yes, it freaks some people out. Is is technically murder? Is it ethical? All of these questions are summed up as "The Transporter Problem". Google that term and you'll find a lot of discussion. It also tends to force people to confront the question of the existence (or not) of an immaterial soul.

Where do I buy the organ filament for my 3D printer?

One of those videos that make me look for the 6 star rating.

Really disappointed to see 29 people disliked this. Really happy to see, there are only 29 of them.

I bet Hewlett Packard is eyeing the developments on that one. I can just see the marketing strategy: "for your everyday office needs or that tricky organ failure emergency"

Thanks, this is great!!!

I have read something about 120 years or so as a maximum. But as I said before there is still the danger of cell mutation that can shorten that lifespan.

Great job !

IF this could be masterd it would be the greatest acomplishment in medicen EVER!!!

i think education of any sort is meant to lead you to make progress in life

I'm not asking anyone to exclude the word from the vocabulary, rather, I'm advocating proper use and awareness of overuse. I don't know why you people are defending it so much, he used the word almost every other word, it was obnoxious. Sometimes, people need to learn a few more words, then they don't overuse words. It's the same with 'literally', people like to use that word WAY too much.

Incredible. There is hope then, that many of us will celebrate our 100th birthday, wearing a new meatsuit:)

This is unbelievable!!!

3d列印終究只能列印單一細胞或是死細胞，人體器官由很多種細胞組成，而且做出來以後是要移植的，所以勢必要用需要的人的ips call去做出器官，所以想做器官用3D列印是wrong，應該用拚豆的方式，將不同的細胞一個一個慢慢拚起來，cell->tissue->organ 。

I am blown away, this is absolutely ingenious

Yeah, sorry I didn't really help raise the level of discourse in my exchanges with him. I'm done now, so hopefully things can return to normal. "Thanks for the support." No problem.

Errrrr.... that wasn't science dude, that was your TV channel. World of difference, buddy.

The medical reasons for circumcision are highly suspect. Slicing off healthy body parts just to prevent infection makes very little sense, especially when the infection is not life threatening.

Incredible.

this is AMAZING!!!

I clicked on the subtitles for this video. Are the subtitles automated or typed by a person? The translation is really bad, sometimes it's WAY off, and the sentences don't make sense. Is there a way to put a correct translation on the video subtitles? I want to use this video as a point of discussion for my English class and they need the subtitles to follow the speech.

find a way to 3dprint collagen while spraying different mix of cells that suit the needed organ ... problem solved

How is making organs 4 years later?

Dr. Curt Connors has tried this.

COME ON! WHAT IS IT GONNA TAKE TO GET THIS READY! COME ON PEOPLE!

This is ridiculous. And by ridiculous, I mean ridiculously cool!

Thanks friend This Ted vid is climbing Sooooo fast =-)

Holy cow! well done!

good work

I counted... Actually: 47 times Actual: 2 times I also thought he sounded like that one Tim Conway character from the Carol Burnett show...anyway. But that was a VERY interesting talk nonetheless.

Someone needs to make a demotivational poster saying something like 'when's the last time you prayed and regrew an organ .... Where's your god now?'

You don't have to be so rude and angry toward people's comments. Chill out.

How can you not be? I try my best to stay conscious and never ignorant. It doesn't always work out, but i still try. There are many great words, which should be used according to the best fit for the context of the sentence. In some cases, people forget this, and try to reuse the same word for every sentence. "I seriously had to seriously do something, seriously. He was seriously coming after me" For some it's 'actually'. Although, it is a correct sentence, it isn't an intelligent one.

Is it possible to invest in the whole liver regeneration aspect of his research? I may need a new one in twenty or thirty years.

he says ¨actually¨a lot actually.

That may be true for a lot of things, but I stringly doubt this for the elongation of our lifespan. Besides the above just consider mutations that occur more and more. Maybe we will find a way, but I think it is unlikely.

Where in Europe can i learn it. In Europe because in USA studying is so expensive.

Technology has come far, but where is the access for people to get it. People are still on many organ lists. 🤷🏽‍♂️

This is awesome. And it wouldn't be possible without SCIENCE!

Very interesting... only problem I foresee is that yeah sure, he can make you a new finger or heart valve or probably larger things eventually, legs, arms etc... What about Nerves?

Since 1.4 million healthy newborn American boys are having valuable body parts amputated against their will every year, the market for this technology is bottomless for the foreseeable future.

Cheers.

we could use this too replicate different types of blood too! really cool stuff.

This is amazing and wonderful. So many people, and so many families will be changed for the better in the future because of this technology. I hope no corporation or religion decides to vilify the research in the public eye for some selfish reason.

Could this mean we potentially could grow organs that we do not already have or extra/enhanced limbs maybe?

After producing the heart cells on the printer I was sure he was going to say: "Please don't try this at home"

I heard bomb too... and was thoroughly confused until i realised he meant balm. T_T

I don't know why i don't like?!

Awesome, absolutely amazing. This century, we will have to decide whether humans have the right to immortality, crazy stuff.

"Actually"

I wanted to buy shares of one of those companies but.. So it's only the growing up of cells they have created. I was thinking they could figure out how the salamander regenerates and try to apply it, I would like to make it as on a computer to grow up an organ only by having the DNA information :).

we will see wont we ?

Amazing.

Nice video!

Really great

Anyone else notice Patch Adams in the front row?

No, I'm becoming increasingly surprised how many people take offense to me just simply pointing out the overuse of a word by the speaker. He uses it every other fucking word, it's true, get over it. I'm a knight of observation. You guys are like the black knight, just don't know when to quit.

@Urglab Quote: "We are stardust" That's a great line from Crosby, Stills, Nash, and Young, but just because there is some great hippie music about it doesn't make it true. ~_^

No, there's not obviously an intelligent design that brought us here. That kind of thinking goes back a long long time. It's the reason why humans thought they were the center of the universe. We're not special, we're made of the most common elements in the universe. We are stardust. And that is much more interesting than thinking some intelligence "made" us.

what seems impossible today is possible tomorrow
