This would be done by taking DNA from the patient and fusing it with an empty egg cell.
Certainly, something unusual is happening in the process by which the egg cell sends out signals to reprogram its new nucleus and put the developmental genes back into action.
This begins with a stimulus, such as an electric shock, that promotes the fusion of an egg cell that has had its nucleus removed with a donor cell whose nucleus it will assume.
Sir Ian and his team fused the genetic information from an adult sheep cell nucleus with an egg cell to form an embryo that developed into a genetically identical copy of the original adult.
With only the genetic material from the person to be cloned inside the shell of the egg, the cell would be jolted with electricity to activate cell division.
Both breast-fed and formula-fed babies who had been given n-3 fatty acid enriched egg yolks had 30-40% greater red cell membrane DHA levels than those fed normal egg yolks.
The success rate for creating an embryo by injecting DNA from a donor cell into an egg was 1 in 15, far more than researchers had previously thought possible.
Reproductive cloning, which created Dolly the sheep in 1997, involves transferring the nucleus of an adult cell into an egg, giving the resulting embryo a full set of genes without the normal sperm-meets-egg fertilisation step.
In the case of the northern wombat, the nucleus could be taken from an easily accessible skin cell, and the egg could be provided by a common wombat.
The adult cell whose nucleus was transferred into the egg that became Dolly had a male imprinted genome that was inherited at birth and copied to every cell of the donor's body.
The scientists first removed the DNA from an unfertilized human egg, and then inserted a patient's mature skin cell containing the patient's DNA into that egg.
In the future, Mitalipov anticipates it will be possible to produce a stem cell line from each donated egg.
But Sir John showed the wisdom of Dr Brenner's choice when he discovered that (sex cells aside) adult worms all have 959 cells in them, and that the pattern of cell differentiation which leads from egg to adult is the same in every individual.
ECONOMIST: This year, the Nobel authorities have shown a deft touch
The cell is then given a jolt of electricity to activate cell division, basically tricking the cell into doing what a fertilized egg would normally do.
But critics of human cloning and stem cell extraction methods essentially believe a human egg that begins to divide for any reason should be considered an embryo, and a potential person, that deserves protection under the law.
Then there's a completely new idea, which is to generate a kind of a cell that you would merge with a kind of an egg, and you'd get something that was kind of an embryo but it wasn't really an embryo, and it wouldn't have the potential to grow into anything, and maybe those would give rise to stem cells.
Scientists say DNA taken from a cell in the ovary of an adult camel was put into an egg from a surrogate mother.
To create each embryo, they took the DNA out of an egg, so that it was hollow, and replaced it with the skin cell's DNA instead.
Then the nucleus of a cell -- any cell in the body -- is taken from the individual to be cloned and inserted into the egg.
