How New Bioreactor Technology Advances Lab-Grown Meat Production
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A new bioreactor using hollow fibers successfully grew over 10 grams of realistic cultured chicken meat by mimicking a circulatory system to deliver nutrients throughout the tissue.
📈 One key stat: The bioreactor produced more than 10 grams of chicken muscle tissue using 1,125 hollow fibers, representing a significant scaling up of cultured meat production.
💬 One key quote: “Our technology enables the production of structured meat with improved texture and flavor, potentially accelerating its commercial viability. Beyond food, this platform may also impact regenerative medicine and soft robotics,” says senior author Shoji Takeuchi of The University of Tokyo.
1️⃣ The big picture: Scientists have created a breakthrough bioreactor system that makes lab-grown meat more realistic and scalable. The system uses hollow fibers, similar to those in water filters and dialysis machines, to deliver oxygen and nutrients throughout artificial tissue – mimicking how blood vessels work in real meat. This overcomes a major hurdle in cultured meat production where tissues thicker than 1 millimeter typically couldn’t get enough nutrients to survive. The technology enables growing larger pieces of meat with better texture and structure.
2️⃣ Why is this good news: The technology brings lab-grown meat closer to matching the taste and texture of conventional meat while offering a more sustainable and ethical protein source. By enabling larger-scale production of cultured meat with improved properties, this advance can help reduce environmental impacts from traditional livestock farming. The bioreactor system also shows promise for medical applications like growing replacement tissues and testing new drugs. The use of common materials like hollow fibers suggests potential for cost-effective scaling.
3️⃣ What’s next: Researchers plan to improve oxygen delivery in larger tissues, develop automated fiber removal processes, and transition to food-safe materials. They aim to use artificial oxygen carriers to mimic red blood cells, create bundle-removal mechanisms for efficiently removing fibers, and develop edible or recyclable hollow fibers. The team will also study the long-term effects of perfusion on tissue quality and work on enhancing the mechanical properties to better match natural muscle tissue.
