An anonymous reader writes: According to Reuters, "Using a culture method previously tested to grow mouse embryos outside of a mother, the teams were able to conduct almost hour by hour observations of human embryo development to see how they develop and organize themselves up to day 13."
Brave new world, here we come From the report: "The work, covered in two studies published on Wednesday in the journal Nature and Nature Cell Biology, showed how the cells that will eventually form the human body self-organize into the basic structure of a post-implantation human embryo. As well as advancing human biology expertise, the knowledge gained from studying these developments should help to improve in-vitro fertilization (IVF) treatments and further progress in the field of regenerative medicine, the researchers said. But the research also raises the issue of an international law banning scientists from developing human embryos beyond 14 days, and suggests this limit may have to be reviewed. 'Longer cultures could provide absolutely critical information for basic human biology,' said researcher Zernicka-Goetz. 'But this would of course raise the next question - of where we should put the next limit.'"pdiv class="share_submission" style="position:relative;"
