Yes, genetically modified sheep have been used to produce medicinal proteins in their milk that help treat diseases such as haemophilia and emphysema; for haemophilia, the sheep produce clotting factors needed to stop bleeding, and for emphysema, they produce alpha-1 antitrypsin, a protein that protects the lungs from damage.
Genetically modified sheep have been developed to produce medicinal proteins in their milk for treating certain diseases. Two diseases targeted by this technology are:
Hemophilia: Genetically engineered sheep, like Polly, were created to produce human coagulation factor IX (FIX) in their milk. FIX is a blood-clotting protein deficient in individuals with hemophilia B, also known as Christmas disease.
Emphysema: Transgenic sheep, such as Tracy, were engineered to produce alpha-1 antitrypsin (AAT) in their milk. AAT is a protein used to treat hereditary emphysema and cystic fibrosis caused by a deficiency in this protein.
