How to make LAB GROWN MEAT – Synthetic Meat Production

lab-grown meat is coming with at least three companies releasing products to the market in the near future lab-grown meat does not need to be genetically modified this may be the start of a new age a second domestication of animals where just the muscle cells are grown without harming the animal wasting animal parts and greatly reducing the impact of the meat industry on the environment the meat industry is responsible for around 50% of all greenhouse gas emissions growing livestock uses around 25% of available land and very large parts of freshwater reserves meat is easily contaminated and human and animal interactions can cause the jumping of diseases like avian flu and the meat industry causes vast amounts of animal suffering with the livestock stuffed into tiny spaces in addition the meat industry is the biggest consumer of antibiotics leading us to antibiotic resistance and an era of super bacteria but we’re nowhere near getting lab-grown meat cheap and widely available this is the very beginning let’s see how that grow meat is made and what the challenges facing – – field scale production arm let’s take a look at the basic process for culturing meat a sample of meat is taken from an anesthetized animal adult muscle stem cells also known as satellite cells are separated from the sample these cells are then grown in an environment that resembles the animal body as close as possible with oxygen and appropriate nutrients present in the growth medium that is the liquid surrounding the cells the growing of these cells can be divided into two phases first the stem cells are replicated to grow their number and then the replicated cells are ushered to develop into muscle cells this is how white posts research group from the University of Maastricht made the world’s first cultured hamburger costing around two hundred and fifty thousand euros or three hundred and twenty five thousand dollars the price was this high because the burger was made of around twenty thousand tiny strips of meat separately hand grown and then combined we can’t grow blood vessels to the cultured muscle cells to supply them with oxygen and nutrients and that’s why the cells could only be grown in very thin layers for muscle cells to grow they need a framework to attach to one method that’s looking promising for growing muscle cells in an industrial scale is to use small beads as the framework for the cells to grow on that the beads can be made of starch that is carbohydrates or collagen the protein in between cells and tissues or other similar materials these beads can float in the growth medium and thus muscle cells are not limited to going on a flat surface beads are small enough for oxygen and nutrients to be able to reach all cells growing in the bead another obstacle to growing a meat artificially is the fact that animal serum that is blood with the blood cells and blood clotting protease removed has been traditionally used as part of the growth for medium it provides the cells different factors they need for a growth but it’s expensive and not something you’d want to used on an industrial scale the companies rolling out lab-grown meats have researched animal-free growth mediums intensely and companies like memphis meats and just inked both claimed that they have come up with alternative solutions to make things trickier cells from different species need their own animal free growth medium recipes the cow satellite muscle cells seem especially picky and have been difficult to grow without an animal growth medium according to just in the first product teaching the markets in 2018 is going to be something avian the starting stem cell line is also something that is crucial to get right the satellite adult stem cells can only make more of themselves or turn into muscle cells they can’t make bone or fat cells etc and they can only divide around 20 times another cell type that has also been studied for the starting material of muscle cells are pluripotent stem cells pluripotent means capable of many things the core important stem cells have the capability to become many more cell types than just muscle cells in fact they can make all the cells in the body and they can divide unlimitedly unlike the satellite cells since their satellite cells can only divide around 20 times new cells have to be harvested from animals once in a while in contrast a pluripotent stem cell line is like sourdough yeast once you have it going you have it poeta the only problem is that we don’t have a pluripotent stem cell line from a cow taking embryonic stem cells from a cow is possible but it’s proven difficult to keep the cells going on in the lab induced pluripotent stem cells are also an option here a specific set of genes is artificially activated in a cell like a fat cell and this turns the cell into a pluripotent stem cell it’s really a fascinating topic and absolutely deserves a video of its own induced pluripotent Pig cells have been used to produce muscle cells and this has been done without animal serum another alternative would be to immortalize the satellite cells making them capable of infinite cell divisions an effective way to immortalize a cell is to turn on the gene producing to telomere repairing telomerase enzyme telomeres are repeating DNA the end of chromosomes that shorten as the cell divides the more the cell divides the shorter the telomeres get when the telomeres are short enough the cell can’t divide anymore activating the telomerase enzyme in the cell fixes the shortened telomeres giving the cell infinite life but this requires genetic engineering and marketing the Meade product gets more difficult even when the cells can effectively be supplied with nutrients and oxygen the growth medium is perfected and cell lines are optimized for muscle cell production the end product is not going to be anything close to a steak it’s going to be a mass of cells resembling minced meat a lot of research is directed towards perfecting the taste by growing fat cells with the muscle cells and finding ways to stimulate the cells to produce lots of protein but the taste of meat is determined by around a thousand different chemicals and part of the taste comes from what happens to the meat when butchered it forums lactic acid its pH drops and the tissue breaking proteins start working getting lab-grown me to resemble a steak is still far off but this technology is taking its very first steps with time and it may drastically change the way we consume meat assuming that the public is willing to embrace a technological solution to one of the great problems of modern society although growing meats in a lab can be quite energy intensive at least in the beginning the huge potential for lowering fresh water and land use limiting methane emissions from cows animal welfare and safety our goal is to strive for thanks for watching if you’re liking the content and want to help this

  1. Sorry to everyone, but there just isn't anything that's ever gonna beat a big ol' juicy steak. If this works and it gets cheaper to make I'm all for it, but it's not replaceing my steak

  2. A very well done video. Do you have any sources for someone interested in reading further into pluripotent stem cells? Keep up the good work!

  3. Facinating video! I probably wouldn't eat lab-grown meat, but that's because I don't eat meat. But it's nice to hear that people are trying to find new solutions to one of the big problems of today.

  4. This is so well made. I'm an aspiring bioengineering major (on top of being vegetarian) so the topic really resonated with me. Keep up the great work with this channel. Just subbed and shared 👍

  5. came here from the kurzgesagt video about meat, great idea to advertise yourself there 😉 really nice and informative video i hope you'll get a lot of views soon 🙂

  6. This is a spectacular video, especially considering the size of the channel! I can't believe I'm here this early on! Please keep making great content, as, at least in my estimation, more videos of this standard almost guarantee success.

    Also, I'm gonna quickly mark my place as a sub 1k subscriber so I can brag about it in the future!

  7. what a great video, saw your comment on the Kurzgesagt video and just watched your video. they pretty much told everything you said in this video but they didnt go in much detail about lab meat like in this video, Keep the video's coming man! +1 sub

  8. Interesting video! I've been thinking for a long time that the current meat and dairy industry has to be phased out at some point. Great to hear that there's progress being made!

  9. Great Video and channel, really appreciate the work you put into the videos. Btw came here by your comment below Kurzgesagts video.

  10. I came here from Kurzgesagt's "Why Meat is the Best Worst Thing in the World 🍔" and I am super impressed. You earned yourself a new subscriber. This is great content! You deserve millions more subscribers if you keep this up.

  11. I mean, I'm fine with Lab-grown meat as long as it tastes similar to actual meat, you know? But I am definitely excited for this kind of research continue, even though I was just made aware of this problem of meat with Kurzgesagt's video.

  12. What this is NOT telling you is, this was started in 2013,,,5 yrs ago and they want it ON THE MARKET by 2020. They STILL haven't done research into the Health Effects of this on the human Body. Brain, Liver, Kidney, Heart, etc. What happens if we find out LATER that it's bad for us and WHO will take responsibility for the damage it may do to our Health? Remember, a Decade or so ago we were TOLD the High Fructose Corn Sweeteners were "A safe alternative to Sugar"..only to find out after it was put into just about EVERY food product we consumed It was NOT safe. Fatty liver Disease, Obesity and other SERIOUS health Problems have been linked to this product. So much so that soda and other food companies have switched BACK to sugar  secretly to protect against law suits. Will "Clean Meat" be just another product FORCED on us that will end up causing us to be sick, or maybe worse? Why no Human Testing? Why did the FDA approve this without first Testing it? Way too man questions and NO Answers are given. NOT GOOD. Oh and BTW, Bill Gate and Steve Branson are pushing this,,,they have ONE WORLD interests and also believe in World Population control. Let that sink in a minute. Question, do THEY eat this too. Or do they have the "do as I say and NOT as I do" approach. Just like Big Tech Companies that won't let THEIR KIDS have Tech Toys in Their PRIVATE SCHOOLS?

  13. I simply can not believe how well made this video is, splendid editing and audio-visual usage, simple yet thorough explanation of the topic and referencing of every single thing. I am truly in awe, subbed immediately, keep up the good work!

  14. Your videos are really interesting, informative, and generally really fun to watch! I would like to ask you if there is an other way to communicate with you because I am a part of a scouts group in Greece and we want to make a project about meat in vitro, and since you have researched it so much we would be glad if you could help us by answering questions either in email, video call or something similar. Thank you in advance.

  15. I love meat, but I am also aware of the huge impact that the meat industry inflicts. I would give this stuff a try.
    It's interesting that the industry as it now exists is essentially an animal version of a concentration/death camp. Many animals are crammed into a small space, standing in their own filth, injected with antibiotics. There are slaughtered, butchered and bled in unsafe (at least sometimes) and unsanitary conditions where cross-contamination can spread disease vectors across an entire country.
    Meanwhile, lab grown meat is considered gross??????

  16. Small sidenote: Tune down background music considered to your Voice. Its kind of unbalanced 😉

    (First seconds/minute its very off)

  17. This video is so underrated, wish I could discover it earlier saving me from reading tons of academic papers
    FYI, now there are lab-grown steaks out there created by 3D bioprinting

  18. When it hits the stores at a reasonable price, even if higher than a normal meat, me and my gf will totally go for it. Nothing better than enjoying a stake created without animal suffering and cruelty!

  19. I came here from your comment on the Kurzgesagt video, must say I'm glad I found this channel. Tolles Video 🙂

  20. Great explanation, thank you. As a vegetarian I am extremely exited about artificial animal products.

  21. just for talking about this particular topic and explaining it this good, your channel sub count should be multiplied by at least 100.
    Very underrated video of a very underrated channel.
    As a person who's really concerned about the main causes of climate change, i am very impatient for lab grown meat to become the norm

  22. I came here from kurzgesagts complement system vid comment section…. I was expecting a mediocre channel with bad editing…. But man….. Was I wrong!
    You definitely deserve more subscribers!
    Hope your channel grows!
    Dunno the requirements if any…. But you should be on Patreon

  23. Absolutely disgusting, any idiot backing this needs to look at how society was duped into allowing GM foods to be created and then put in the food chain….. be careful what you wish for, your being poisoned enough by those white jackets in labs, I just can’t believe how stupid and ignorant today’s society is…. meat grown in a lab pffffffft, clowns the lot of you……

  24. As a (mostly) ethical vegetarian I have to express relief that Science usually resolves moral quandaries if research and academic examination can be supported properly

  25. Would introducing reverse telomerase transcriptase into the initial stem cells be a way to immortalize them? Why is immortalizing the cell considered genetic manipulation if the result is exactly the same gene, only with longer telomeres? How would you differentiate a cell immortalized in this way from, say, a fetal cow muscle cell? If there is no way to differentiate them, then what is the problem? I honestly don't understand the resistance to GMO since natural mutations happen all the time, some of which are beneficial, just like a GMO. Another solution would be to raise a generation of humans that isn't so reliant on animal proteins. There are so many alternative sources that are also very tasty.
