However, rejection of new organ became a problem. That’s when Cyclosporine which was discovered in 1972 came in, which is extracted from a species of fungus and was found to prevent the rejection of a new organ in mice. Thereafter, Cyclosporine was tested on dogs that have undergone organ transplant, thus resulting in a 3-times increase in survival rate. What’s animal testing has done for humans?
