Researchers at Hebrew University and Believer Meats reported a method to naturally immortalize bovine cells without genetic modification by activating telomerase and PGC1α, enabling stable self‑renewal and mitochondrial regeneration. The study, published in Nature, demonstrates a non‑GM path to generate scalable cell lines for cultivated beef production. The approach addresses a central technical and regulatory bottleneck for cultured meat—establishing safe, stable cell sources without transgenic alterations. Authors led by Yaakov Nahmias noted the process parallels prior chicken work and may ease regulatory scrutiny tied to genetically modified cell lines. Commercial translation will require reproducibility across breeds, stability studies, and safety assessments. If adopted, the technique could accelerate scale‑up and lower cost of goods for the cultivated meat industry.
