1st put, assembled living cells to a place desperately needed human organs. stay with us for that time, sir kelly in berlin. thank you for watching the votes. people have to say the that's why we listen to based on the ritual every weekend on d. w. fast fashion as an environmental 9, a clothing graveyard, immature land desert. this is where things wealthy industrial nations no longer

need and flight us textile ways get stranded fashion. watch now on youtube, the right now, hundreds of thousands of people around the world. a waiting for organ transplants like 4 year old, a v. green who's been waiting for a new hoc for a year will smart technology revolutionized organ transplants. and all 3 d printed organs anywhere close to becoming the norm. find out on shift is a hot made from human cells using ice 3 d printer scientists, intel of they have already made this breakthrough back in 2019. the printed hot couldn't be yet, but it was assigned the researches were on the right path. the key here is printing using living cells, so called by printing type d printing. well, the other 23 d printing, also known as additive manufacturing,

has been in use an industry and for a number of years up yet, it basically means building complex objects layer by layer hiding young and a few years ago. and this trend also made its way into the field of biomedicine told us in all we've been equaled up in the enables those to print the layers of living materials. and that's my logical material. teeth which are very complex material properties. these thing all fixed wires and for the whole phone, cutting the ones that we now have new possibilities and file medicine complaint can hopefully print complex oregon structures in the future. using 3 d bio printing. all the bio printing just for the bar printing had system. so science is can actually print organs using living cells. that's pretty incredible. in 2022, the 1st 3 d printed it was transplanted into a volunteer in the united states. but that was the last we heard. we reached out to the company 3 day by a therapeutic several times for an update on the current clinical trial without any

luck, but this much is clear the race to manufacture functioning organs using 3 d printer has been going on for years. first attempts to fly printing artificial organs were made over 2 decades ago. one of the trail blazes is us surgeon, dr. anthony atalla. in 2011 a 3 day printed accuse me. thus the organ is measured using m r. i scanned the daughters then use to create a 3 day model which has been sent to the printer. the printer manufacturer has the model layout by layoff, from living cells, all as shown here from plus the race such as, as noting. and trent university develop basically the using a 3 d printer in 2021. it looks deceptively real, but it's actually made of synthetic materials. it's supposed to help train doctors to recognize live at cancer. in 2020 to 3 day systems and united therapeutics presented

a 3 day printed long structure. this synthetic creation should help regulate gas exchange. the way healthy lungs do, animal testing should offer insight into how it functions. it will probably still take some time before 3 d printed organs will actually be able to replace traditional organ donations. but this technology is already proving to be very useful in medical research today. like this 3 d printed bought a cop made from synthetic material. researches at the massachusetts institute of technology in the united states have developed a road, bought a car using a 3 d printer. the replica is supposed to emulate the functions of a patient's individual heart research as 1st create a 3 dimensional computer model using data from the patients hot. it's made up of soft, flexible, synthetic materials. the artificial heart is wrapped in slaves that mimic a hot date. h one is controlled separately to ensure that it pumps realistically,

this way the rug bought a car and mirror a hot date of the patient. researches one to hone in on how the patients hot use contracting. robotics is not meant to be transplanted. instead, it's supposed to help does better understand the hot conditions of individual patients. and therefore, i pinpoint the best treatment very helpful for treating people with hot conditions, but not a solution for patients waiting for an actual hot transplant. still 3 day by printing can be deployed in other ways. lots of patients who need a bypass due to blocked vessels, researches in northern germany, a testing out there. so i did investigate with surgeon dr. ivan benz on his team of developing a new procedure speaking and fees isn't in artificial vessels, are in a georgia dream and surgery from the eligible company. and one of the

cardiovascular surgeons, you and have typically end up in a situation where you're caring for a patient, but don't have any suitable material to use for to bypass. and, for example, i must, i'm for a heart bypass or a bypass and the leg. and researchers have been working for many decades now. i'm creating by artificial vessels in the line. so standing level, it would enable us to help perform a bypassing patients that don't have the necessary part of the material. i expect them to bypass and meet with the research team. so idea, a princess single tenuously presses to liquids to create a flexible, to made of bio materials that's roughly 30 centimeters long. one of these liquids is so called via when it's a positive volcanic think that's enriched with even investigating cells. it's guys, this is an elgin, a material made from brown out not drawing back to the cell generates a step. so as country bind well to it, that's why we have peptides which are small pieces of proteins that can be found in

the human body like college and you need to pay for something that bind to these peptides cubic. even the pep side can also send signals to the sales forces so that they feel comfortable and can survive and reproduce and bianca after and initial phase using standard straight print is. the team is now switching to a robot with a specially developed printed one chain. the in the print head contains the biling . while the other contains calcium, fluoride stabilizes the bypass graft process. elective. i'm this may look relatively simple, but it actually requires fine shooting a lot of different parameters and power allows the. i'd also don't have one challenges that bio into does not have no technic properties. in other words, it behaves differently from typical liquids becomes more solid to under pressure eva. um, by just means we need to equip the printed both resistors here to ensure a uniform flow of the by a wing venus. and who move in flows. the few instead of allies,

it's all incredibly delicate and precise work. so it's no surprise that the researches have carried out countless test prints. one challenge, the entire structure needs to have a consistent thickness for this evening. but if you take a look at this bypass and you can see how much it sends out and the size length of yes and on the other 2 sides, you can see that it's quite sick on the inside, right? so it won't hold up on those are the more symmetric, the structure, the stronger the circular structure, the more stable it will ultimately be. what is this? that'd be the best of the artificial bypass cross supposed to be as uniform as possible so that they can function inside the patients the decades of the printing . the new structures must mature in a nutrients solution as 37 degrees. for a few days, we usually print type room temperature, that's where it is the same,

but keeping the cells at room temperature for a long time can be detrimental to the cells nathan selling lessons. so we print using this substance, we on the bike and then we place them in san to bio reactive, where the culture is kept at $37.00 degrees. the item is for as many cells to survive the printing process as possible. if everything is going smoothly, numerous green cells become visible under the microscope. in the next lab test phase, bypass graft a being tested in animals. clearly a controversial ethical issue, but the scientists say it's necessary. and on that topic, 3 d printing with living cells could i sleep even help to replace animal testing. for example, when developing new drugs, pharmaceutical labs could use so called organ on a chip models. these devices can emulate how human organs function thanks to by a chips the need for animal testing could soon be reduced. the cells on so called organ on a chip systems biologically,

mimic human organs. when they come into contact with active agents. instead of animal testing, researches are increasingly using these kinds of many labs. it helps them to sun, if substances toxic to the human body or whether they could work as medications. the system basically consists of a microscope slide, at least one cell culture and micro channels. the membrane works as a carrier for the cell culture, while the micro channel supplied with f nutrients and active agent pot live. uh, excuse me, cells can be grown onto the chip or printed on the slide. using boiling sensors allowed to sign system monitor the condition of the cells home the chip. many of the bar trees have also started using coaches from multiple organs on the same chip, reducing the number of tests. today, there are even chips with complex 3 dimensional cell structures. which allows for more precise testing. 3 d printing using living cells,

certainly books very promising. of course it would be even better if we could print cells and organs exactly where they needed inside the human body. and scientists are already making big strides. check it out. this is an experimental meaning 3 d bias for tool could directly print by material until opens and one day it could be deployed inside the human body. we can directly deliver multiple and they uh, they only table inside the big body and quite the coloring. melvin $10.00 a they have to make well material outside of the body and then it'll go to the lady but the material they have to be quite when it says read a bunch and ready to decline as also fiction. and look last similar to an endo scope. the soft and flexible robeteck is inserted into the body either through the mouth and a small, a small skin incision using bio ink. the device can print by material on to organs

and tissues, for example, to repair them. often injury so this is a larger version of our 3 default printer. we have this is basically used to, to, to live up on materials to the end side or off of the surgery to facilitate to the healing process. we have a camera located at the tip for the visualization, as we can see right here. and we have one channel at the top, 2 for the delivery of the materials. and up to the fact we have the control us to control the bending of the printer and it doesn't lead print. it can also make any decisions and spray water to clean the wounds after an operation in the future. this medical tool could be use for different types of surgeries, including the removal of cancer risk. janice, it basically did defy,

can utilize on in one set of co device they can before them the, and course a big surgical procedure. and therefore, they can do more to sit and tie up kinds of timble inside the bodies. i think actually article on kind of sense. there is so much of groundbreaking research going on right now. but what people who are waiting for an organ transplant need the most is more open donors would you're doing night, your organs, or do you say 3 day printed organs as the way of the future? let us know. and so you next on the pico africa, ruby's ear is still and it's making people say it's important for us to begin

collecting this data to be able to compare it and see whether there's any health impacts. and this little device as opposed to how we quoted these a low cost of what the team does it more eco africa next on d w, have you ever heard the term jump? ha, this basically describes how masses of young people are leaving the country to search for better opportunities elsewhere. when skilled work is leave africa, they leave a program of grand, great, big. it's hard to appreciate the real part of this problem. we sent out our team of correspondence to find some answers. this 77 percent. been 60 minutes, the opponent d. w gets ready for an exciting auburn toyota to look surprised. hi, irish. and i'm ready to die into the hands of the gentleman who 2 of you,

one you have you have a one to talk to me before you go to the boss and the on expected side to side the how can we improve life in all of cities with more and more people across africa and around the globe moving to other areas. this question has never been more important. i am sandra co homes, a 3 know do a writing comp. welcome to yet another exciting edition of eco offered. and i chris a lives in legal side to area on the show today. we'll look at how we could clean up la cities making life better for ourselves and our environment.
