Transgenic cows boost human insulin production by 10X


A genetically modified cow has produced milk containing human insulin, according to a new study. The proof-of-concept achievement could be scaled up to, eventually, produce enough insulin to ensure availability and reduced cost for all diabetics requiring the life-maintaining drug.

Using the upper dose of ten units, based on Wheeler’s calculations, a liter of transgenic cow milk would provide me with enough insulin to cover 2,881 lunches – very nearly eight years’ worth. Wheeler says that even a small herd of human insulin-producing cows could quickly overtake existing insulin manufacturing methods and do so without the need for highly technical facilities or infrastructure. “With regard to mass-producing insulin in milk, you’d need specialized, high-health-status facilities for the cattle, but it’s nothing too out of the ordinary for our well-established dairy industry,” said Wheeler.
