“The nuclear transfer(核子移植)of one species to another is not easy,and the lack of available(capable of being used) panda eggs could be a major problem,”Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy(having a baby).It takes a long time and it’s difficult,but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk,so it is worth the effort,”adds Kraemer,who is one of the leaders of the Project at Texas A & M,the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done,and this is very similar to our work in Noah’s Ark.We’re both trying to save animals that face extinction.I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do.It’s a research that is very much needed.”
