Use of a drug selection eliminates those stem cells with nonhomologous recombination products. Viral vectors, microinjection, T-DNA, electroporation, and biolistic transfer. Used a nucleus from a terminally differentiated cell type. Created using constituitively expressed DNA from genetically unrelated species.
