Xenotransplantation
The first known xenotransplantation was done by the god Shiva. Daksha, the father in law of Shiva, organized a yagna. He insulted Shiva and his daughter. Sati, Shiva’s wife, immolated herself in protest. Daksha’s head was cut off and burnt. Later, when Shiva forgave him, he was brought back to life but with a ram’s head. The more famous decapitation was that of Ganesha. Shiva cut off the head of a baby elephant and transplanted it on to his son’s neck.
For the last 300 years doctors have been trying to replicate this miracle. The process is called xenotransplantation, or the transplanting of non-human organs or cells into a human body.
Thousands of animals have died in the process. And each attempt has been a failure. But that doesn’t stop scientists from trying. After all, animal life is cheap and, in the name of science, one can do anything.
In the 17th century, Jean Baptiste Denis started the practice of blood transfusion from animals to humans. Everyone died and xenotransfusion was banned in France for a number of years. In the 19th century, skin grafts became relatively popular between various animal species and humans. The fact that many of the species used as donors—sheep, rabbits, dogs, cats, rats, chickens, and pigeons—had hair, feathers, or fur, growing from the skin, did not deter the surgeons involved. The ideal graft was from frogs, which were sometimes skinned alive. None of the grafts were successful.
In the 20th century, the French experimental surgeon, Alexis Carrel, developed surgical techniques for joining blood vessels, which enabled organ transplantation to be carried out successfully for the first time. For this work he was awarded the Nobel Prize in 1912. He developed an interest in crossspecies transplantation and his techniques became a reason for more people to experiment on animals.
