World’s first 3D-printed steak

Scientists Reveal World’s First 3D-Printed, Marbled Wagyu Beef

Scientists from Osaka University have manufactured the world’s first 3D-printed Wagyu beef by using stem cells isolated from Japanese cattle, according to a press release. The product looks like a realistic steak piece containing muscle, fat, and blood vessels.
...
The researchers used two types of stem cells, bovine satellite cells and adipose-derived stem cells, insulated from Wagyu cows, according to the paper published in the journal Nature Communications. Then, they incubated and coaxed the cells into becoming the various cell types required to generate individual fibers for muscle, fat, and blood vessels. These were piled into a 3D stack to resemble the marbling of Wagyu.

Then, the researchers adapted a technique inspired by the one used to produce Japanese Kintaro candy, an old traditional sweet formed in a long pipe and cut into slices. The stacks were sliced perpendicularly to form lab-grown beef slices, which allowed a great degree of customization within the complex meat structure.

Nature Communications: Engineered whole cut meat-like tissue by the assembly of cell fibers using tendon-gel integrated bioprinting

Abstract

With the current interest in cultured meat, mammalian cell-based meat has mostly been unstructured. There is thus still a high demand for artificial steak-like meat. We demonstrate in vitro construction of engineered steak-like tissue assembled of three types of bovine cell fibers (muscle, fat, and vessel). Because actual meat is an aligned assembly of the fibers connected to the tendon for the actions of contraction and relaxation, tendon-gel integrated bioprinting was developed to construct tendon-like gels. In this study, a total of 72 fibers comprising 42 muscles, 28 adipose tissues, and 2 blood capillaries were constructed by tendon-gel integrated bioprinting and manually assembled to fabricate steak-like meat with a diameter of 5 mm and a length of 10 mm inspired by a meat cut. The developed tendon-gel integrated bioprinting here could be a promising technology for the fabrication of the desired types of steak-like cultured meats.

Re: World’s first 3D-printed steak

For RobertDyck re new topic ...

Best wishes for success with this promising new topic!

It will be interesting to see if this applied research is successful in the market place. 

Even if the method remains on the expensive side on Earth, it would seem likely to become the least expensive alternative ** away ** from Earth.

Plain algae may be less expensive, and there may well be plenty of humans away from Earth who subsist on it, but I'll bet that the possibility of high quality food will provide incentive for productive activity on the part of off-world workers.

Re: World’s first 3D-printed steak

Whether you want to grill, pan-fry, or broil your steak, practice makes perfect!

What’s at Stake: Choosing the Right Cut of Steakbuy-usda-prime-large.jpg

13 Different Types of Steak – Do You Know Them All?types-of-steak-July202020-2-min.jpg

  • Main Types of Steak
    1. Tenderloin (aka Filet Mignon)
    2. T-Bone
    3. Ribeye
    4. New York Strip
    5. Hanger Steak
    6. Flank
    7. Tri-Tip
    8. Prime Rib
    9. Flat Iron
    10. Wagyu Steak
    11. Top Sirloin
    12. Skirt Steak
    13. Brisket

If you are an absolute steak lover, you’d know what makes a great steak, and how to identify one from afar- a big, fat, beautiful slab of beef. When coupled with delicious garlic pepper sauced, creamed spinach, some sautéed vegetables, and perhaps, a glass of chilled drink, it is like a party in your mouth with your taste buds dancing all around with utter glee.

Wow! That's truly incredible. I think this could definitely be the way forward for meat eating on Mars.

Re: World’s first 3D-printed steak

If they can 3D print steak, then how about a muscle?  Why not a replacement heart, or liver?

Re: World’s first 3D-printed steak

For Calliban,

Please try to find the time to read the original article !!! It may help you to answer your question, and then perhaps help you to imagine what might be possible.

I too find your question important and worth pursuing, although I suspect there's a long journey between here and there !!!

Re: World’s first 3D-printed steak

Here is another Israeli firm MeaTech prints 3 oz steak, composed mostly of real cultivated fat and muscle cells

AARByop.img?h=768&w=1366&m=6&q=60&o=f&l=f

Israel-based MeaTech 3D has succeeded in bioprinting a 104-gram (3.67-oz.) cultivated steak, primarily composed of real cultivated fat and muscle cells. This is, according to the company, the largest cultivated steak comprised of real, living muscle and fat tissues, without using any soy or pea protein.

I think I've watched too many sicifi dystopias as I didnt expect the steak to look that well

Re: World’s first 3D-printed steak

Plans are underway to build the world's largest cultivated meat facility. Growing 13,000 tonnes of chicken and beef a year, the technology could reduce the huge environmental impact of livestock farming

Cultivated meat has the potential to transform the way we produce protein.
