Transgenic cow in Brazil produces human insulin in milk, revolutionizing insulin production.

A transgenic cow in Brazil has become the world's first to produce human insulin in its milk. The groundbreaking development, led by researchers from the University of Illinois Urbana-Champaign and the Universidade de São Paulo, could revolutionize insulin production and potentially eliminate drug scarcity and high costs for people with diabetes. The mammary gland's protein production efficiency can now be harnessed to produce insulin to help millions worldwide.
