Researchers injected the growth factor gene VEGF164 and the bone protein gene BMP2 into the ligaments and tendons of horses that had gone lame due to injury.
VEGF164 enhances the growth of blood vessels, while BMP2 plays an important role in the development of bone and cartilage.
Both the genes were derived from horses, resulting in the synthesis of natural horse proteins in the treated animals.
Within two to three weeks, the horses were able to walk and trot.
Within just two months they were back to full health, galloping and competing.
