"Transgenic Cow Produces High Levels of Human Insulin in Milk"

Scientists have successfully created a gene-edited cow that produces human insulin in its milk, offering a potential solution to the global insulin shortage. The cow, born in Brazil, unexpectedly produced both proinsulin and insulin in her milk, with the equivalent of a gram per liter. The team aims to scale up production by having the cow go through full lactation cycles and potentially creating an insulin-expressing herd. This breakthrough could revolutionize insulin production, potentially outcompeting other methods and providing a sustainable supply for the world's needs.
