Researchers have made significant strides in cultured meat technology, potentially transforming how we produce meat while addressing ethical and environmental concerns.
A team led by Professor Tatsuya Shimizu at Tokyo Women’s Medical University has developed a groundbreaking system for cultivating muscle cells without relying on animal serum, traditionally essential for cell growth but fraught with challenges related to cost, contamination, and ethics.
Published in Scientific Reports on August 23, 2024, the study explores a co-culture system that combines growth factor-secreting rat liver cells with modified photosynthetic microorganisms, specifically L-lactate assimilating cyanobacteria.
This breakthrough addresses ethical concerns and environmental impacts while meeting global food demand.These microorganisms not only provide essential nutrients but also play a crucial role in waste management by converting harmful byproducts, such as lactate and ammonia, into beneficial nutrients for muscle cell growth.
This innovative approach yielded remarkable results: the co-cultured supernatant from the liver cells and cyanobacteria significantly enhanced muscle cell growth rates—three times higher than using liver cells alone.
By reducing harmful waste products by 30% and over 90%, respectively, the researchers demonstrated that this method can provide a sustainable and cost-effective alternative to serum.
As global food demand escalates, such environmentally friendly technologies are vital for ensuring food security.
The implications extend beyond meat production, with potential applications in fermentation, bio-pharmaceutical production, and regenerative medicine.
By enabling meat production without animal slaughter, this advancement not only addresses future food challenges but also contributes to ethical considerations and climate change mitigation.
As Professor Shimizu states, this research represents a novel, sustainable approach with broad applicability, promising a new era in cellular agriculture.
