Came back to this video today as I read a new article today that they tested a pig kidney on a brain dead donor body and it worked! It worked almost immediately and is a great start for more trials! We must praise the lovely 🐖
Very unfortunate that it comes from animal often considered as dirty by some cultures and religions.
@@HadiTR23 why are you hatin' on me? I know. As I said, it's a shame it's from a pig.
@@HadiTR23bruh what are you saying? no ones stereotyping, sensitive over nothing
buddy of mine got a animal valve as a baby, had to get it replaced 15 years later but is otherwise perfectly healthy. Pretty amazing.
Thanks to science 🧫!
I need a kidney transplant and that’s why I am here seeking information. Hopefully I get get a xenotransplant soon!
@@Lima547
Best wishes from Scotland.
@@Lima547 Best result for your health, Bro
I hope you get a new kidney and live a great life!!! And be healthy and have fun
@@Lima547 yes sir
And while you're under the knife you could get an ink pouch to help you escape from enemies.
LOL
Morec0 Depends on your preference, I prefer hiding in my shell (if you ask them nicely to make it just a little bigger you can even store snacks in it!)
Drakan R Yeah, but then you have to worry about cleaning it, making sure the snacks don't expire. With an ink pouch all you have to do is squeeze it out every once in a while so that the stuff doesn't get overly sticky and gunk you up.
Morec0 POCKET SAND
I was going to comment on the viability of an ink cloud in air as a means of concealment, but I suppose if someone I was chasing squirted a jet of black gunk out of their backside at me, I'd let them go too.
I actually have had a pig valve in my heart for years & never knew the actual name of what the doctors did until this video. Thank you!
For those that may not want a pig valve or may have religious objections to pig valves there is also the option for bovine (cow) valves. My mother had rejection problems with the pig valve and the doctors substituted a bovine valve and she went on to live for about another twenty years.
Wait, she died?
@@somebody_2837 Humans die over time. It's called aging.
@@chrismanuel9768 I thought she died of rejection of the heart valve, not aging.
I accompanied a friend to cardiology appointment, one of options doctor talked was mechanical valve too, but fecker is noisy.
OH HANK, I'm so disappointed in your writers:
Did no-one think of *"And that's how Pigs could one day Save Your Bacon"* as an outro line?
I have cow bone in my jaw. That was a weird conversation with the dentist.
Tryo707 Wow, sounds cool. Why would you get that kind of transplant?
Genetic deterioration of the bone. Human bone would just get eaten away. Bovine bones aren't attacked.
Tryo707 Geez, sounds bad. At least the transplant worked.
Nick Nirus bone is dead and there is nothing in the area that can kill you instantly if you do something wrong, so i assume it's a relatively easy transplant, but i'm not an expert so i might very well be wrong.
Bone is alive
My mom went through a valve replacement last year. Watching this video and understand a little better how it's done... it's terrifying and amazing. Science is amazing, and i'm so thankful for all the research that made possible the one surgery that saved her life.
they actually recently performed a full heart transplant on a 57 year old with a pigs heart. the guy survived for about 2 months before subsiding to cancer. the doctors say that the death was not related to the pig heart
just had my heart valve replaced earlier this year. it was interesting to find out the science behind it
Dude if it saves thousands of lives i hope they continue this line of research, hell, i’d probably donate my parts to someone uncomfortable with having animal parts if it got to a point where there was almost no risk to me
Organ donation happens after you're dead, so no risk for you
Depending on the country you live in you need to fill in a form declaring your organs may be used after your death but that's it
I wouldn't mind going around with a pig's heart or lung or something. Imagine the interviews:
"Do you have any special traits?"
"Yes. I am part pig."
"...what?"

THIS. THIS IS WHAT I WANT TO DO WITH MY LIFE. This is why I'm in school right now and studying engineering. One of my professors is doing research on this exact topic and I'm hoping that I'll be able to work with him on the research in the next couple years. Thank you for posting this!

Charlie'sGayBand I think that would be a xenoimplantation.
Charlie'sGayBand Actually, if aliens abducted you, took you to their planet, and forced you to grow crops... you would be on a xenotransplantation.

"The downside? some people would feel uncomfortable" there you go people and their useless feelings.
"It is also quite expensive." oh alright now we are talking.
thank you for making this video! This is a really cool subject. especially when one of my brothers works on genetically modifying pig embryos to stop them from producing genetic markers that alert the human immune system that the organ is not human. And another one of my siblings had an internship, where they essentially created kidneys for transplantation using decellurization (removing the cells of an organ and replacing them with the donors cells). Anyways thank you for making this, I enjoyed it so much. Thank you!

Another way to solve the organ shortage: Make being a donor the default, and people can opt out of it, instead of the opposite.
Being a dead donor that is. Because people give organs while they're alive too. But i do want to be given away to those who need it if i die in good health. But i think most family members and loved ones deal with death bad enough that they shouldn't have to deal with the thought that the close family payed at least $1000 extra to get the poor fellow restuffed with cotton or something in the abdomen for the viewing to net disturb tbe guests. I'm not sure if it's possible to use stuff from the face or head, but for cosmetic thinhs like an ear i could imgine fir like a burn victim or sg. So the dead would be totally disfigured. I mean they won't mind now, but they'r lived ones might. That's why after they gave what they could to others from me i either wanna be cremated and spread, but my family has a tradition of putting the urnes in our family grave. There's my granma granpa, my dads ex wife, my granmas sibling i think and my sister. I feel weird about being a pot of dust sitting in a grave but tbh it might be beautiful if i can hang out with the others in the afterlife without mental illnes or diseas. I could get to know the sister i didn't get close to. My alive sister and i often eonder what her opinions would've been on certain things. So back to what i was saying either cremation or i saw a video of this thing a startup wanted to bring back. They would put the body in fetal position if possible. Put the body in a breathable sack the sack is multiple layer and in a little pouch there would be seeds sewn in. That way after they lowered you in a beautiful tree would grow above you. It is good for smaller children from your family understanding that they're visiting you. It's scary and grim for a child to be at a semetary where they most likely don't really understand. Your lived ones can come out and take care of the tree as they remember you. Sorry for getting way offtrack. So i like the idea of post motum donations.
@@juliakercsmar6587 During autopsy all the internal organs are removed and inspected by the medical examiner and then placed back inside the body or sometimes incinerated. At the funeral home, the mortician removes the viscera and places it in a plastic bag called a “viscera bag” and allows it to soak in the embalming chemical.
This should be on crash course biology because i have to learn this for my Bio alevel at school, great video btw
Hi, I know in Boston they have engineered and installed new bladders for thirty women at McMasters university but I hear the progress is going slower on solid organs. They also have grown working mouse kidney's, not sure where.
I need a kidney myself but I'm O- and the wait times worse than comcast on a holiday:) There don't seem to be any effective treatments to keep kidney function going till a transplant can be found. Dialysis is damaging to the body and only a stop gap measure at best anyway. Glad Hank's bring awareness to the subject.Thanks.
I was expecting to be able to get gills or a tail.. Disappointed.
I want to get ears and tail
Mr. Spanky and I refer you to the end of the comment and my hand, because litteraly the so called bate has no hook to speak of. Laugh all you want, I'm here for honest talk and I enjoy it either way regardless of whether Mr. Spidiot thinks avoiding responsibility but repeating a psychological issue is even comically dignified. In fact, to reference an old (and albeit out of context) phrase, I can see and smell your dirty underwear from here, coward homophobe.

This is precisely what we're talking about in my life science & ag class right now. Perfect!
Wow. The good this will do when its been fully developed. Many people die on a waiting list. Talk about waste not want not. We could use the entire animal. I knew that pig hearts are similar to human hearts ( that's why we use them in classes) but I did not know that we were using their valves to replace human ones. Stem cells keep proving to be an awesome discovery. The possibility of growing our own spare organs is amazing. Doctors at the time of birth are asking mothers if they would like to save the umbilical cord for its stem cells. One day it may be that you can walk into a hospital needing an organ and the doctors can pull your stem cells from birth and start growing a new one and have it implanted. No rejections, little drugs, and no waiting lists.
Sooo what you're saying is: bacon is good for us?! Yay!
This video has taught me more than I have learned from an entire day at school.
My grandma got a valve from a cow inside her heart. She's still kickin' and sassy as ever lol
Hi Hank. HAPPY BIRTHDAY. I watch ALL yr shows from crash course to scishow to all yr other series. Thank you for all the shows. have a great birthday.
Christopher n Trisha (Singapore)
First pork chops, now a new heart to replace the one that was clogged by the pork chops?! Aren't pigs amazing!
When can I get wings?
***** Even with wings (big ass ones you'd need) you'd need the stamina, the new muscle tissue etc to use them. Then you'd need Stabilizers on your feet to keep you stable and control your pitch in flight, so you'd end up looking like this hideous massive human being with a 30 foot wing span that weighs over 100lbs and has muscle bulging from everywhere and winglets hanging off your legs/feet.
Or you could just get 2 little wings thrown on for visuals.
sacr3 I'll just have a Red Bull.

How 'bout those Snakes on your head, Medusa?

My mom had a heart valve transplant ,but hers was bovine. I have heard that equine valves have also been used in some cases. These things never cease to cause me to marvel at modern technology. Thank you for the very informative Sci Show today!
man i'd be so much more comfortable with having chicken eggs falling out of me every month instead of blood and uterine lining
Sounds like the possibility of Orcs happening, isn't zero.
My bf has a heart valve he’s had it ever since he was 16, and he’s 25 now, and it still going really strong.
This one Olympic runner got his Achilles’ tendon replaced with a wallaby’s
Really? I googled that and couldn’t find anything at all.
PETA would find a way and condemn this. They'd rather save a pigs life than a humans life.
MrWhataboss23 I don't think you mean "condone" based on your 2nd sentence.
MrWhataboss23 I think you mean "condemn"

Petards, they're so retarded
Samuel Stormont You assume that English is the OP's native language? I think that Breyana1313 found a better and more polite way to comment on the troll's error.
You should also make a video about the auto-transplants, in some ways research is more advanced in this field. For those not familiar with the term, auto-transplant or auto-grafting means using the patient's own cells to grow replacement organs or tissue outside the body (in the lab).
As far as I know we can't grow whole hearts or kidneys yet, but for simpler tissues like skin or cartilage we're already doing if for some time now. A few years ago I personally participated in a cartilage auto-grafting clinical trial that ended with a complete functional procedure being perfected. I'm just a radiologist, so my contribution was negligible, but the clinical team is using this procedure to heal joint injuries ever since, with over 90% success rates. The only real problem remaining is the cost, even if it's cheaper than allo-grafting (transplants), auto-grafting is still pretty expansive compared to most classic alternatives.
Thank you SciShow for posting this video on the same day as my Transgenic exam, right after I wrote it. We had an entire lecture based on Xenotransplantation XD
this kind of reminds me "The Island" the movie where there is a whole society of clones who live just in case their original humans ever need a transplant.
I expected seeing people implanting wings or something.
Silent Joe Shit, that sounds hype!
It would probably require a lot of body alteration to fly, though.
Silent Joe They'd need pectoral muscles the size of their torso and hollow bones. Doesn't sound like such a good idea to me.
Big wings needed

I’m watching this 3 years after it released, clicking on it because of a personal connection.
When my Father was first born they gutted him like a fish (his words not mine 🤗), cut out a chunk of his digestive system & replaced it with Pig parts. He spent the first six months of his life in hospital (his parents weren’t even allowed to see him 😳) then when he returned home he was fed with a spoon & couldn’t be held..... in fact a nurse came twice a day to change his diaper & check his bandages.
As my Father is a VERY private person & getting any information out of him is like pulling teeth (seriously, it once took me nearly an hour just to get him to tell me my Mother had left to get Groceries 😤), this Video offers me some insight.
Sounds like a good way to get extra parts like a tail. Furry anyone? =P
yessss!
Lemony Tail would probably get in the way a lot and make you unbalanced.
we already have a tailbone, but why no tail?
it was an add-on to the comment i already knew that, but thank you. (it was more of a rhetorical question)
I can think of plenty of uses for a tail so idk.
Wings would be nice, but unfortunately as primates we aren't built for flying.
okay, but when can i become part wolf
lol same here
I am altogether impressed and surprised at the conversations this video prompted.
Way to go people keeping discussions civil and only hate ranting against "uneducated idiots who slow science down (or something along those lines)" instead of at a specific individual.
I can't believe I didn't see the puns coming.

Could you guys do an episode on Homosexuality? Or have you already? Or would it be way too controversial for what you guys feel like handling?
I worked in researching this with kidneys for a time. It's a long ways from entire organs, but I was impressed by the powder they made from pig bladder tissue that human cells would actually move into! Used for healing war & burn victims.
Have they refined this treatment enough for it to be used on a regular basis for such terrible injuries? Burns are some of the hardest things to treat since the scaffolding is destroyed along with the skin cells and the risk of infection is huge. That's not to mention the terrible pain involved in the very lengthy healing process. I'd love to know more.

I think this is by far the most amazing thing that I've ever heard! Believe it or not I am 34 yrs old and had never ever heard of XENOTRANSPLANT until I decided to donate bone marrow! This just blew my mind!
This just made me think of a weird slightly philosophical question: Say a person had a transplant from a pig or some other animal then years later the person was killed by someone who then ate just the part of the person that was transplanted. Would the murderer be a cannibal or not?
Yes because they killed and harvested the part from a human. It doesn't matter where it came from before that; a human is dead and part of them had been eaten.
People have issues with transplantation of animal parts? But what would you rather? Pig heart or die? Gosh.
Jessicaisrealawesome It works like this: "Well, all those people should just get over theirselves, and bear their illnes, it's unethical! How disgusting" -> *Moron gets ill* -> "Doctor please save me, what ever the cost, please please!"

good vid guys I hope to see more follow up's O7
I had a porcine heart valve transplant in 2002.
I wonder what the cost of animal life is for this. All of the unethical lab experiments just to test this.
Danny O'keefe all i hear is bitching and whining
Freezing Blue Ditto most human lives are worth more than animals specially the two legged kind.
Danny O'keefe Sometimes the well being of many humans outweigh the death of a few animals. Its sad, but that is the reality in which we live. Besides, what other species on the planet has the potential to save life on earth and transplant it to other planets to ensure its continuation? To me, that is the ultimate goal humanity should be striving for. At least for now.
Danny O'keefe You have to ask yourself the question. If you or a loved one developed a fatal illness that could be cured by a drug or treatment that was developed through animal testing, would you refuse the medication and let the ill person die?
If you would take the treatment, then you justify animal testing. I'm not saying either choice is right or wrong, but when the decision is made personal, most people will accept the cost of medical experimentation on animals to prolong the life of a loved one.
Bob MiLaplace your comment is like Animal Farm but reversed (4 legs or wings = friend).
some day people will have to buy mass produced low quality organs because they destroyed their own with mass produced low quality meat. Kinda funny. feel sorry for all of those pigs however.
That is definitely possible but there might be other factors involved. Not all health problems are because of diet. There might be genetics, behavior and environmental causes for disease.
How about we clone humans in a secret facility convincing the clones that there was a catastrophic event that wiped out humanity and when an organ needs transplanted to a patient we tell a clone that they have won a ticket to go on holiday but we actually harvest their organs...this would make an awesome movie
You need to go to an ISLAND to clear your mind
Or we just clone the individual organs and save the trouble?
killerklipz awesome movie indeed, I see what you did there (now if only I could remember the name).
How about no because thats a crime against humanity, the island sucked anyway
I liked The Island, it reminded me of Logan's Run.
My grandmother was implanted with a bovine aortic valve. Her transplant lasted for several years, however I theorize that it ultimately led to her demise once it started to wear out.
I am 100% Against this. Genetically engineering pigs and slaughtering them for their heart? This is extremely sickening and masochistic to me, I would want nothing to do with this. I don't value my life as any more precious than any other animal's.
Jason Klein are you aware this isn't tumblr?
Well I don't care, if we weren't better than pigs we wouldn't be able to do it but we are.
Ethanwhitby123
Yes, dismiss a different opinion as tumblr instead of with a cogent rebuttal.
do you eat meat?
I assume you have a better way to deal with shortage of organs then
I'm super excited that one day I'll get a new heart and it will be grown in a lab that's just TOO AWESOME but then again my heart isn't quite bad enough for me to require a transplant but WHATEVER I'M STILL EXCITED
LOL thats funny, I was just watching the episode of ST:next generation where Worf gets a new spine printed for him.
thought i would pause it and see what SciShow has been talking about
Must...resist...yiffy thoughts!
So this was put up 7 years-ago. Yes, a lot has advanced since then, but there's a long way to go. I hope we get to the next stage soon!
and i reask my question from 1 year ago... WHEN CAN SCIENCE GIVE ME BIRD EYES!!!
'not comfortable with pig organs in them' ooh yeah let me just die
Your hair is on point sir!
Alpha Gal sounds like a superhero.
Next thing you know, we're going to have our own version of Organ Inc. raising a hoard of pigoons...
this made me start thinking of Repo! the genetic opera :s hopefully it wont come to that though
I want to see a study comparing peoples thoughts/feelings on transhumanism or biomechanical enhancement against thoughts/feelings people have regarding animal organs in humans.
I've had lymphoma so I could never be an organ transplant person but heads off to people who do because we desperately need them for patients
Dear Scishow, I have two questions that have always confused the crap out of me:
1. What makes a relative a second cousin or once removed or any of that?
2. What the heck are lymph nodes?
10/10 would watch again
Xenotransplantation has helped many people that couldn't get other human parts. Heart valves work even when the cells in it are dead. The process of being able to use more animal parts is slowly evolving. Most people are uncomfortable with the thought of having an animal part in their body, but if that was your only choice to live you would take it. If this becomes more researched it could help out in the medical world tremendously. I am for all for more research for this, if it will help save more lives then why not do more research in it.
You wouldn't want a transplant from a mouse, or a beluga whale. HAHAHAA Hank, you made my day hahahahhaha
Hank!!! your hair!! it's different - I like it! 👍👍👌
good video, by the way.
Xenotransplantation is a great topic. hope you can do more!
Happy 420BLAZEIT
Similar to what you were saying I saw this cool thing where they were 3d printing simple body parts like ears with the 3d printer's "ink" made out of some concoction I didnt understand too much besides that it contained cells from the patient so they could attatch it to the patient and the patients own cells would eventually recreate the body part.
But yeah only for simple things like ears that are basically just cartilage and skin so far, not complex organs.
greatest video i ever heard
SciShow do you know how long on average the heart valves last nowadays? I may be having one this year and id like to know more
I'm imagining having a heart transplant from a pig or something, then serving said pig for dinner after the operation.
I kind of wish we still had tails... "NAPPA" lol
THE HAIR HANK, THE HAIR! I like it, it's classy 😎 welcome to the club.
"private jet level of wealth" that should be the official classification in the tax code~ XD
Um.... Before this video I got an ad for a "Paragonix SherpaPak"... which is apparently some sort of "cardiac transport system" and it was this weird container for an actual heart?? WHAT.
I'm a registered organ donor and I have told my family to let doctors have any part they want. That simple conversation with my family, whilst not the most comfortable, might save a life.
I think that using animal parts to replace a body part that someone is in need of is a great idea. I think that more emphasis should be placed on researching the possibility of more than simple dead tissues such as heart valves. Animal organs are obviously much more readily available an easier to come across since animals are killed for food anyways. If we were to completely figure out how to transplant animal organs to humans, thousands of lives would be saved yearly. There would be virtually no wait. Obviously there will be people that think its unethical to place the organs of animals into humans, but it is a great alternative.
love this episode :D
