Researchers Develop Hollow Fiber Bioreactor to Improve Cultivated Meat Texture and Scale

Researchers at the University of Tokyo have developed a bioreactor that mimics a circulatory system, improving the production of cultivated meat by ensuring even nutrient and oxygen delivery to tissues. This new approach, utilizing semipermeable hollow fibers, enables the creation of centimeter-scale chicken skeletal muscle tissues and a 10-gram piece of whole-cut chicken meat. By preventing necrosis in thicker tissues, this innovation addresses key challenges in scaling up cultivated meat production and could lead to improved texture and flavor, making cultivated meat more comparable to conventional meat.

The technology has the potential to accelerate the commercial viability of cultured meat, offering a sustainable and ethical alternative to traditional meat production. Beyond food production, the hollow fiber bioreactor could also have applications in regenerative medicine and biohybrid robotics, supporting the development of functional tissues and even organs. Challenges remain, such as improving oxygen delivery in larger tissues, automating fiber removal, and transitioning to food-safe materials, but the research team is optimistic about the future possibilities of their technology in various fields.
