Cultivated beef breakthrough: Scientists overcome cost and technical barriers
Scientists in Israel have developed a method to naturally “immortalize” cow cells without genetic modification or abnormal transformation — challenging long-held beliefs that genetic methods are the only way bovine cells can renew themselves. The discovery addresses one of the most stubborn bottlenecks in cultivated beef and lamb production by providing a “safe, stable, and scalable” source of cells for sustainable and ethical meat production without the environmental toll of traditional livestock farming. While similar self-renewal has been achieved previously in chicken cells, this study overturns previous assumptions that such processes were not possible in large mammals due to their natural resistance to cellular transformation, says the team at the Hebrew University of Jerusalem and Believer Meats, who jointly conducted the research. The study’s lead, professor Yaakov Nahmias from the Grass Center for Bioengineering at the university founded Believer Meats in 2018, which partnered
