This is fascinating, though the idea of destroying a female embryo to show that females could reproduce is sort of grotesque.
The researcher is applying for permission to use stem cells from bone marrow instead of embryos because it would be more practical, which leads me to wonder why it was necessary to try with embryonic stem cells first, and if it was easier to get permission to do so. (Certainly, women who want to produce sperm to fertilize another woman’s egg aren’t going to be doing it from an embryonic state.)
Overall though, this is really cool.
The article explains that sperm was created from male cells previously. The problem with creating sperm from female cells is that the information to do so is in the Y chromosome.
