1.   Conceptually, of course, cloning by embryo splitting is much simpler than cloning by nuclear transfer.

2.   Instead, he had simply made new embryos by nuclear transfer.

3.   The outcome of nuclear transfer can vary a great deal, depending on which of these courses is followed.

4.   There seems to be no a priori reason why nuclear transfer should work.

5.   They announced the birth and subsequent good health of three cloned mice, created by nuclear transfer.

6.   Thus they achieved nuclear transfer without ever penetrating karyoplast or cytoplast at all.

7.   We produced four live, cloned lambs by nuclear transfer.

8.   An empty egg is fused with the nucleus of an adult human body cell to create an embryo in the process called nuclear transfer.

9.   A somatic cell nuclear transfer is not about joining sperm and egg to create a unique human being.

10.   Even so, researchers hoping to publish work on nuclear transfer in humans may now have to come up with better evidence that embryos are healthy.
