What are the Advantages and disadvantages of bone marrow transplantation?

Answer 1

The main advantages:

- Many organs occur once within the human body and are critical to life. e.g. the heart. If an organ fails then the only option is to replace it with a donor heart. Animal hearts (if they could be used) could be farmed specifically for medical purposes and thus resolve many issues over donor organ availability (which currently has to wait for a donor to die in such a way that doesn't damage the relevant organs to be donated).

- If animals could be used for transplants then many health / lifestyle decisions would be significantly less important. e.g. drinking alcohol damages the liver. However, if liver transplants from animals were readily available then the damage to the body from alcohol consumption would be less significant.

The main disadvantages:

- Practically this isn't possible due to differences between animals and humans (proteins mainly) which would cause the animal donor organ to be rejected, identified as foreign tissue and ultimately attacked by our bodies immune systems.

- There is a significant risk of infection from using non-human organs because a pathogen considered benign within the donor may be deadly / serious for humans.

- There are ethical issues over the use of animals in this way, especially when people's own lifesyle decisions (e.g. obesity) result in the deaths of potentially hundreds of thousands of animals per year.
