| No organs from transgenic pigs have been transplanted into humans. There are very strict requirements that need to be met prior to approval by national regulatory bodies of novel clinical approaches. In particular authorities want to be assured of the results with transgenic pig organs in non-human primates before they will give the go-ahead for the initiation of experimental clinical trials. Public acceptance of this procedure will also be essential. Furthermore, there is also the need to demonstrate that pig organs will not lead to infections once transplanted into primates. |
