Biopharming uses genetically modified animals and plants to produce important human proteins for medicine : 

Through recombinant DNA techniques, scientists insert human genes into the genomes of organisms like goats, cows, or crops such as rice and tobacco. These transgenic organisms are then able to express the desired protein in their milk, eggs, or plant tissues. For example, goats have been engineered to produce antithrombin, a blood thinner, in their milk, which can be purified and used to treat patients with clotting disorders. In plants, human enzymes and antibodies can be produced at large scale, offering a cost-effective and safer alternative to traditional cell culture systems. Biopharming holds great promise for producing complex therapeutic proteins in large quantities, especially in areas with limited access to expensive manufacturing infrastructure. As this field evolves, it could greatly expand global access to life-saving biologic drugs, vaccines, and enzymes.
