It highlights various methods, including the development of knockout and "knock-in" mice, alongside successful transgenic sheep, goats, chickens, pigs, and primates. These animals can produce therapeutic proteins, exemplified by sheep producing human proteins in milk and chickens capable of cost-effective protein production in eggs.
