The biggest problem is maintaining the pregnancy. |
The bottom line is very simple: Can you clone a dog? Absolutely. But it is extremely inefficient and extremely expensive. |
We worked on it for like two-and-a-half to three years and basically had very similar results to what was published in Nature (on Wednesday). The problem with the dog is their unpredictable reproductive cycle. That's what makes them such a difficult species to clone. |
We're a long way from actually getting an animal down on the ground. The main thing for us was to work on and adapt the technology. |
