Researchers at the University of Cambridge, UK have succeeded in reconstructing mouse embryos by combining pluripotent embryonic and multipotent trophoblast stem cells in a 3D scaffold; the study from the laboratory of Professor Zernicka-Goetz, recently published in Science, provides a break-through tool to probe early mammalian development outside the uterus. Achieving a similar feat with human cells might necessitate reconsideration of the 14-day rule as a limitation of such research.

在体外用成分干细胞重新组装胚胎。


英国剑桥大学的研究人员通过将多能胚胎干细胞和多能滋养层干细胞组合在3D支架中，成功重建了小鼠胚胎； Zernicka-Goetz 教授实验室的这项研究最近发表在《科学》杂志上，为探索子宫外早期哺乳动物的发育提供了突破性的工具。利用人类细胞实现类似的壮举可能需要重新考虑 14 天规则作为此类研究的限制。
