Some examples of genes that can be used in gene therapy:
1. Tissue growth factor-beta (TGF-β): It promotes new blood vessels and epidermal growth. It is useful in wound healing and the treatment of burns.
2. Tissue plasminogen activator (TPA): It is used to prevent or reverse blood clots.
3. Human blood clotting factor VIII: It is used to aid in the clotting of blood and to treat patients suffering from haemophilia.
