In a groundbreaking development, scientists in Brazil have discovered a promising method to address the shortage of insulin, potentially making it more accessible and affordable for those in need.
According to a report from the New York Post, researchers have successfully modified cows to produce human insulin in their milk, offering a novel approach to tackle insulin scarcity.
The lead author of the study, a professor of animal sciences at the University of Illinois, emphasized the efficiency of the cow’s mammary gland as a natural protein factory. By harnessing this system, the researchers were able to produce a protein that could benefit millions worldwide.
Published in the Biotechnology Journal, the study involved integrating a human DNA segment into cow embryos, ensuring that the precursor to insulin is only active in the mammary tissues of the cows.
Through genetic engineering, the researchers achieved a significant milestone, with the genetically modified cows producing milk containing both proinsulin and insulin—a development hailed as “magical.”
Remarkably, the mammary glands of these cows processed the proinsulin into active insulin independently, showcasing the animal’s ability to produce and purify insulin.
The ultimate aim of the research is to establish a herd of transgenic cows capable of surpassing current insulin production levels without relying on high-tech facilities.
The lead researcher highlighted their goal of refining the lactation process to produce an impressive one gram of insulin per liter of milk, a feat that could revolutionize insulin production.
