To solve this, West proposed «therapeutic cloning» — taking the nucleus out of a patient's cell, transferring it into an egg cell to create a cloned embryo, then using that embryo to derive patient - matched stem - cell lines.
Consequently, a fundamental argument against using embryonic stem cells and therapeutic cloning can not be derived from existing constitutional law and additional court decisions.

The researchers in Oregon say they used those cloned monkey embryos to derive embryonic stem cells.
Using cloning technology to derive embryonic stem cells genetically identical to a patient is potentially very important, not only to provide a source of cells that may be used to cure patients, but also to allow for genetic disease to be studied and potential drug treatments to be explored in the laboratory.
To investigate quantitatively whether there are restrictions on cell movement and / or differentiation along the a / p axis, we marked stem cells at a relatively low frequency to avoid generating two adjacent clones derived from different regions.
