Cell-cultured meat is an emerging technology which offers both promising possibilities and substantial scientific challenges.Second, the culture of meat-relevant cells, such as bovine satellite cells (BSCs), has traditionally relied on fetal bovine serum (FBS), a notoriously expensive, unsustainable, and inconsistent component, which is inherently antithetical to the aims of cultured meatThe promise of cultured meat lies in its potential to address environmental, ethical, and human health issues that plague intensive animal agriculture1.
