Mosa Meat cultivates beef without fetal bovine serum

Fetal bovine serum (FBS) is commonly used in cultivated meat production as a supplement for cell feed due to its richness in nutrients and growth factors. But reliance on FBS, taken from the fetuses of pregnant cows during slaughter, is not an ethically viable option for a product positioned as the "environmentally friendly alternative to conventional meat".
In a new paper published in the journal Nature Food, leading cultivated meat brand Mosa Meat reveals how they managed to replace FBS and achieve muscle differentiation without genetically modifying the cells in any way.
This is really a milestone for us and for the cultivated meat field, because there’s no method out there that describes the differentiation of primary satellite cells if you don’t want to use FBS or genetically modify your cells."Dr. Joshua Flack, Mosa Meat scientist
The document includes descriptions of the processes and ingredients of the differentiation medium that worked well for Mosa Meat. The muscle cells that differentiate into fibres are responsible for the structure and chewing of the meat, and it is in the muscle fibres that the protein and rich colour of the meat are produced.
