It's really only by scientists performing some of this essential work on early human embryos that we are going to be able to understand why some embryos make it and some don't. (pacificfertilitycenter.com)
If the techniques work, there are many interesting questions that could be asked about the role of specific genes in early human embryo development, especially as there is accumulating evidence that equivalent stages of embryos from other mammals, notably the mouse from which most of our understanding has come, may rely on the activity of different genes.

Their work will improve our understanding of early human embryo development, understanding which is desperately needed to improve IVF success rates as the authors say, and also to increase the safety of IVF treatments. (sciencemediacentre.org)
