Scientists at Hebrew University and Believer Meats reported a Nature paper describing a non‑genetically modified method to immortalize bovine cells by activating telomerase and PGC1α pathways. The approach yields stable, self‑renewing bovine cell lines without introducing exogenous genetic modifications, addressing a key scalability and regulatory bottleneck for cultivated beef production. The method restores replicative capacity and mitochondrial function, creating a platform for large‑scale cell expansion that could reduce cost and simplify regulatory pathways for cultivated meat. The result signals industrial acceleration for cellular agriculture and may reframe regulatory and public acceptance discussions by removing engineered‑DNA interventions from the supply chain.
