Paving the way for GM humans ?

"Human life could soon be replicated in a laboratory after scientists at the University of Cambridge successfully created artificial mouse embryos."

"Scientist developed a mouse embryo structure using stem cells grown in the lab. The cells grew into primitive embryos that had identical internal structures to those that emerge during normal development in the womb."

"The purpose of the research is to gain deeper insight into an embryo`s development just prior to implantation."

"It marks a significant step forward, as previous attempts to grow embryo-like structures using only embryonic stem cells have only had limited success..."

"If carried out on human embryos, the experiment could reveal the cause behind miscarriages and infertility, as it shows how genetic activity varies the way mammals grow right after conception..."

"However researchers said although the artificial embryo closely resembles a natural one, it is unlikely to develop further into a healthy mouse fetus. This would require a yolk sac, which provides nourishment for the embryo and where blood vessels develop."

"Experiments are currently carried out on leftover human embryos from in Vitro Fertilization (IVF), but these are often insufficient and can only be held for a maximum of 14 days under legal frameworks."

"The outcome of the experiment has also been criticized by some concerned that it may pave the way for genetically modified (GM) humans."

Of course one reason for spontaneous abortion is that it is nature`s way of eliminating an embryo which is not developing properly but the scientists fail to mention that.
