Cell-based products—often called cultivated or cultured—are produced by growing animal cells in a controlled environment rather than raising and slaughtering whole animals. This approach not only reduces environmental impact and supports animal welfare, but also paves the way for sustainable, high-quality alternatives to traditional animal-based products. Innovations in this field range from cultivated meat and disease models for medical research and drug testing to personalized medicine, cosmetics, and leather production—potentially revolutionizing how products are made and consumed globally.
