Japanese Scientists Develop Low-Cost Medium to Grow Muscle Cells Without Animal Serum

Japanese scientists have developed a new co-culturing system using rat cells and modified cyanobacteria to create a low-cost alternative to animal serum for cell growth. This alternative serum not only eliminates contamination risks and waste accumulation associated with fetal bovine serum but also aligns with the goal of producing meat without killing animals. By utilizing growth-factor-secreting rat liver cells and modified cyanobacteria, the researchers were able to significantly reduce waste products like lactate and ammonia, while increasing the growth rate of muscle cells.

The co-culturing system offers a sustainable and ethical approach with various applications in cellular agriculture, including cultured meat production, fermentation, biopharmaceutical production, and regenerative medicine. This innovative technology not only addresses future food security challenges but also ethical concerns and issues related to climate change. The successful findings of this study, published in Scientific Reports, highlight the potential of culturing animal cells with photosynthetic microorganisms to revolutionize the production of meat without harming animals.
