Not being human in any sense, they do not come under this guideline and will help scientists understand how an embryo actually grows beyond this point. He claims this knowledge will help avert congenital defects and spontaneous abortions. They could also help evaluate the safety of drugs in pregnancy.
At present, embryonic research is conducted on residual embryos left unused after in vitro fertilization procedures. While many embryologists and other researchers in related fields agree that Fu has grasped the Holy Grail of human development in the embryonic stage, others are quick to point out the underlying sensitive questions. Earlier research by Fu centered on human pluripotent stem cells, either from embryo or from adult skin cells engineered to resume their embryonic state.
Using chemical signals, these cells, which are of a single type, were induced to develop into other cell types, which is the initial process of embryonic differentiation into different tissues. To increase the gains, the current model no longer uses culture plates.
Instead, the technological heart of this innovation is a thin square tray of silicone with four wells placed around a central narrow channel — a microfluidic system. After putting the stem cells into the device, the appropriate chemicals are added to the adjacent wells, and these stimulate the growth of key embryonic structures, leading to the production of an embryoid in a few days. These embryoids outgrow their microfluidic homes after only four days, and lack many essential cell types, so that they could not be classified as human conceptuses in any case.
With increasing pace of research, however, synthetic embryos that are close to the original natural embryos are sure to arrive sooner rather than later. The burning question for researchers, bioethicists, politicians and funding bodies alike is, will this cross the line that separates human from artificial? Even now, mouse embryos have been created and the fight is on to transfer them into surrogate female mice to generate live baby mice.
No success has yet been reported. However, if human embryos are created, the technology could backfire if someone, for instance, tried to make modified people. For this reason, Fu, among others, has called upon regulators to disallow the use of such models for anything but scientific research — including reproduction using a synthetic embryo. Meanwhile, the exponential growth of stem cell research has pushed a guideline review by the International Society for Stem Cell Research.
The research is published in the Journal Nature.
