"Transgenic Cow Produces High Levels of Human Insulin in Milk"
Scientists have successfully engineered a genetically modified cow that produces proteins necessary for human insulin in its milk, potentially offering a new solution to the world's insulin supply issues. The research team inserted human DNA coding for proinsulin into cow embryos, leading to the birth of a transgenic calf. The cow was induced to lactate, and analysis of its milk revealed the presence of human proinsulin and insulin proteins. The study suggests that a herd of these genetically modified cows could potentially produce a significant amount of insulin, offering a promising alternative to current production methods.
