Well, let's see maybe if you and others like you are lucky, we will have this accurate enough in 15 years, then afterwards we just need to wait 30 more years for FDA approval because government is so fast don't you know.
But he did do it that young man who came on stage had a transplanted kidney from this Dr that was printed!!!! The technology seems to have fell away we should get ahold of this Dr
it's precisely because that it's already 2 years old that it would be quite fascinating to wonder about the status of this technology, especially with the growing commercial use for 3D printing! It's an exciting and inspiring video, and it can have the effect of making you feel good about being human (which, if you look around, isn't always the feeling you would get).
These things move so slow it's unbelievable. This video was made about seven years ago, another one was over ten years ago. I'm a paraplegic that needs a new bladder. I was injured at the age of three, I'm now 60. After being hit by a drunk driver my spinal cord was severed at T-10 complete. I have a neurogenic bladder that has also shrunk. Keeping all these things in mind I need a bladder replacement. Currently there are no studies being done. Even Wake Forest will not be continuing this work for another two years. Since I won't be able to go this route the bladder will have to be removed, my organs rerouted and a whole placed in my side for urinating in a bag. This will be for the rest of my life. Yet.....we have the technology. Why the waiting so long? will it be twenty or thirty more years before this will happen? If anyone hears of any studies please let me know!
Amazing progress talk to a toddler actually I'm rather speechless and the story of the young man actually choked me up and brought tears to my eyes I worked in the human potential movement years ago as a counselor and I have to say there is apparently no limit to what you mean this kind of Chief as in the case of dr. Atallah I dictated these comments boy voice because of vision difficulties and I hope people can understand what I'm trying to say Doctor atala demonstrates that there is no limit apparently to what the human being can achieve
If why haven't things like this been implemented in today's technology every hospital should have one I am on permanent dialysis I could really use a new kidney but I can't get one because I'm an alcoholic and an addict This would be perfect for people like me That will never see a waiting list
i wouldn't go that far yet , although bioengineering will take medicine to a whole new level and will improve and save alot of lives that need it we are not even close to be even dreaming about imortality , imagine for example what would go into printing or repairing a human brain which happens to be the most complicated thing known to man...
I'm really grateful for that disclaimer at 11:27. The speaker misleads the audience by calling it a "printed kidney" when really it's just the scaffold of a kidney. That's a massive difference.
@@Mo-sk7xo A natural organ, such as a kidney, is made up of a wide variety of cell types held together in the right shape by a biological meshwork called the extracellular matrix. You can see this matrix at 6:25 (which is naturally white after all the cells have been washed away). The meshwork is made up of a variety of non-living polymeric materials, which is handy for regenerative medicine scientists because we humans are already very good at manufacturing things from non-living polymeric materials such as plastics and resins and others. So creating an artificial meshwork of an organ, called a scaffold, is the easy bit (relatively speaking haha). On first watching, I assumed the kidney he shows at the end is just the scaffold (i.e. a printed artificial polymer which resembles the shape of a kidney down to the microscopic level) with no actual cells in it. I'd offer the analogy of building a city from scratch without putting any people in it; impressive, but functionless until you can find a way to get people (cells) inside. Cell types needed in solid organs are typically incapable of movement, so you'd either have to insert them into the scaffold whilst you're making it or find some clever way to perfuse the organ scaffold with those cells afterwards --- like they managed to with that piece of natural liver scaffold at 6:25. When I posted this last year, I didn't think it was possible to 3D print the scaffold at the same time as seeding the scaffold with cells. But upon rewatching this an some other videos, I realised that 3D printer ink sometimes use a mixture of scaffold materials and cells, letting the printed scaffold material solidify and polymerize around the cells. I'm surprised this works to be honest; it's a bit like pouring concrete with people in it! He doesn't explicitly say whether that prinetd kidney has cells or not, so I'm not sure. What I do know is it's been 8 years and printed kidneys still aren't viable yet. Sorry this was quite long, it's partly because I don't know your knowledge level on this subject, so please ask if you have any further questions of curiosities!
@@TheRABIDdude Nah you Pretty Much covered all my Questions lol...its Just I Wonder if They Printed certain Exterior Body parts how Would Pigment come Into Play?
@@Mo-sk7xo As in skin colour? I suppose they would have the same colouring as the patient because most of these techniques take the patient's own cells and multiply them in a petri dish before adding them to the replacement artificial organ --- like he described doing with that boy's bladder cells to coat the bladder scaffold they made artificially. Using a patient's own cells ensures a perfect tissue match, pretty much eliminating any chance that the patient's immune system rejects the new organ. The cells would be genetically the same as the rest on the body, and so you would expect them to have the same amount of pigment.
Sure I imagine you already know about the octopus who can regrow an arm that is fully functional I've been bragging about you since I first heard the Ted talk about the arthritis and the bladder Sure you have truly made the world a better place for the human race thank you
A little torn on this one. I have chronic kidney disease and this is really great, but I also think we as humans are now way outliving the natural 'life span' of the species. It's great that we can live longer but can society really survive when people are spending 30-40 years retired?
society is nothing that is natural; tribe of 20-50 hunter gatherers is natural; society is a crazy experiment that we need to continue since invention of agriculture; the answer is to go on with biotechnology and AI and see what comes out of this
To create functional organ maybe the voltage sensitive liquid metal compound are best so it know what it is supposed to do and when does it need to do it ect
*Dr. Anthony Atala* already has done a *_Living Proof-of-Concept_* of this procedure by *transplanting* a *3D-printed* urinary bladder to a 9-year old kid, who eventually grew to become a *playing captain wrestler* of his senior high school. That was the year *1989.* Major advances are expected...
It's very complex and there are so many unknown factors that still have to be researched. This trial had 7 patients and all successes, but a later one by a different group had 10 patients and all failed. Also it can't be understated how fast moving the field is. The knowledge of how cells grow and change today is vastly expanded since 2006.
@@somethinghappened3721 Unfortunately, many medical scientists have become disillusioned with regenerative medicine and openly say that this is just scientific hype.
I'm glad that young man got his engineered bladder and things are working out. He will have a large outlook on life because of it and a large financial bill of debt he will carry with him too.
i have seen this Ted video before but it was ages ago, did it get reupload for some reason or is it the same topic but with updated information about the advances in organ printing. Mhmmmm better watch some of it to answer my own questions :)
this is not a break trough if you looked more into science than just watching ted is that this has been around for a few years, whats a breakthrough is the higgs boson and NASA trying to make a warp engineering
Unfortunately, doctors from real practice, including those from respected medical institutions, told me that it is impossible to grow a real organ. All regenerative institutes are engaged in the getting of grants, not real science. No any real results last 15 years.
i'm with you, but remember what a scientific theory is. scientific theories are the most reliable, rigorously tested, and comprehensive forms of scientific knowledge. they come from hypotheses.
People are trained to think intelligently, just like athletes are trained in strength and endurance. If you feel you are not currently smart enough to understand such things, all you need is intelligence training. -Think in First Principles -Be Objective -Use the Scientific Method -Use the Socratic Method -Be Thorough -Learn more Mathematics -Be Divergent -Look for efficient ways of doing things -Increase your sociability -Self Correct -Extrapolate -Look at things through different perspectives -Analyze all things Smart people don't do anything else outside of this list except stay focused, stay persistent, and work hard. And what they do on this list they do to varying degrees. So do everything and you'll be smart enough to study anything
Probably they wait to post videos like this to gain some sort of perspective on how the research pans out,you wouldn't want something like this to flounder miserably...this or they didn't have a youtube channel 2 years ago and they're still catching up
Could this mean the begin of immortality?If u think about it...u could literally print organs over and over again...then when u start aging and they start failing u simply place new ones.What do u guys think about this?
How can we get ahold of the young man who received the kidney? How can we connect with the Dr.? I know he is 65 and still-working in regenerative medicine. The 3D printer was not available then I believe
So is that all that we have to do?Also do u think we could make like a human cyborg?Am thinking if we could print organs we could easily print an entire being!
