In the clearest possible case, the ANT - OAR cell would differ from a zygote on all of the parameters noted above: The ANT - OAR cell would have a pattern of gene expression that is clearly distinct from a zygote; it would generate a homogeneous population of cells rather than multiple cell types; it would undergo simple cleavage divisions and not produce any multicellular structures.

This hypothesis underestimates the opposing power of the egg cell cytoplasm to reprogram the genes in the donor - cell nucleus.

The OAR proposal uses a variation of therapeutic cloning called altered nuclear transfer (ANT) in which the nucleus of a donor cell (a skin cell, for example), containing the 30,000 genes of the genetic code, is altered in such a way that it produces an epigenetic factor, a protein called nanog.

One of the key caveats at the time, however, was that the technique required the use of a virus to introduce several genes into the skin (or other) cell, and these would remain in the cell, and so might contaminate the resulting stem cell or create cancer risks.
