Three independent research teams have now used cloning technology to make human embryonic stem cells carrying the genomes of existing people. The first announcement, using genomes from fetal and infant cells, came last year. The next two reports have emerged in the past month, detailing human embryonic stem cells that were custom made from cell samples derived from living adults, including a 75-year-old man and a 32-year-old woman with type 1 diabetes.
This repeated cloning of embryos and generation of stem cells, now using cells collected from adults, increases the likelihood that human embryos will be produced to generate therapy for a specific individual. The creation of more human embryos for scientific experiments is certain. Regulatory structures must be in place to oversee it.
