We demonstrate here for the ﬁrst time the successful reprogramming of human somatic cells into ESCs [embryonic stem cells] following SCNT [somatic cell nuclear transfer].
In essence, Tachibana et al. successfully used cloning techniques to generate pluripotent (that is, capable of developing into many types of cell) ESCs from adult human fibroblasts (in this case, collagen-producing skin cells). This method of reprogramming adult human cells into pluripotent ESCs may not only facilitate regrowth of damaged adult tissues, but even ease the cloning of human beings.
Human ESCs are sure to remain controversial, but this biological breakthrough may now cause a tectonic shift the ethical locus of that controversy. The Clone Wars rage on.
