Abstract
Cellular agriculture, an emerging technology, aims to produce animal-based products such as meat through scalable tissue culture methods. Traditional techniques rely on chemically undefined media using fetal bovine serum (FBS) or chemically defined media utilizing specific growth factors. To be a viable alternative to conventional meat production, cellular agriculture requires cost-effective materials with established supply chains for growth media. Here, we investigate hydrolysates from Kikuyu grass, Alfalfa grass, and cattle rearing pellets. We identified conditions that promote C2C12 myoblast cell growth in media containing 0.1% and 0% serum. These effects are more pronounced in combination with existing growth promoters such as insulin, transferrin, and selenium. Overall, the rearing pellet hydrolysates were most effective in promoting growth particularly when in combination with the growth promoters. Our findings suggest that leveraging these materials, along with known growth factors, can facilitate the development of improved, scalable, and commercially viable media for cellular agriculture.
