A Japanese government panel has just taken a huge step into human embryonic research by approving the creation of embryos derived from human stem cells.
To wit, a Japanese panel of experts on bioethics has given the proverbial greenlight to the use of induced Pluripotent Stem (iPS) cells, which can be generated from human skin cells via genetic programing, to create human sperm and eggs, which can then be merged to create viable human embryos.
The use of iPS cells is meant to sidestep the ethical quandary around embryonic stem cells, which are harvested from very early-stage embryos that are usually a product of an unsuccessful In Vitro Fertilization (IVF) process and result in a non-viable embryo.
In what is a critical biosafety requirement, the panel has mandated a 14-day culture period for human embryos created in this manner, after which all such embryos will have to be terminated.
The panel has also prohibited the implantation of all such stem cell-derived embryos into either a human or animal uterus.
Up till now, researchers have only used stem cells in this manner to create the precursor cells to the human egg and sperm, eschewing the next logical step amid a lack of government guidelines, not to mention the specter of rousing an ethical firestorm.
Consequently, this new authorization from the Japanese panel on bioethics is expected to significantly enhance research into possible solutions for problems associated with human infertility and hereditary diseases.
Of course, scientists have already created healthy, fertile mice offsprings from their respective stem cells.
Do note that advanced embryonic research has its fair share of critics, who argue that, with enough research, human procreation might eventually be outsourced to dedicated machines and artificial embryos, which are already in use to support late-gestation babies that undergo premature births.
