Genetically engineered animals offer fresh hope to heart valve patients‼️ Genetically engineered mutations in cows could pave the way for transplant patients to receive whole animal organs in the future. Scientists have used CRISPR to stop bulls producing two sugars that provoke immune responses in humans – and it could help people with red meat allergies.... Scientists have cloned a genetically engineered bull which they hope will help heart valve transplant patients lead better quality lives and benefit people with red meat allergies. Every year, about 300,000 people worldwide receive a new heart valve. Whenever possible, doctors use valves made of tissue from cows or pigs, because the synthetic alternatives can cause blood clots.
