Yan Leyfman: Breakthrough in Engineered Tissue Production
Yan Leyfman, Co-founder and executive director of MedNews Week, shared a post on X:
“Breakthrough in Engineered Tissue Production.
A new hollow fiber bioreactor (HFB) design featuring microscale fiber uniformity has enabled the creation of centimeter-scale, perfused chicken muscle tissue with minimal necrosis and improved structure.
Key innovations:
- Leak-free perfusion enhances cell activity
- Uniform nutrient/oxygen delivery via closely packed semipermeable fibers
- Microanchors guide cell alignment for realistic muscle morphology
- Active perfusion boosts protein expression and sarcomere formation
- Robotic assembly demonstrates scalability
Next steps include exploring recyclable and edible fibers to improve sustainability.
This platform opens the door to scalable cultured meat and large-scale biofabrication, with wide-reaching potential across cellular agriculture and regenerative medicine.”
