Factor responsible for embryo development could bring new perspective for in vitro fertilization

Scientists spent more than a year optimizing their techniques using embryos from mice and human embryonic stem cells before starting ot direct work on human embryos. To inactivate OCT4, they used an editing technique called CRISPR / Cas9 to change the DNA of 41 human embryos. After 7 days, the embryo development was stopped and the embryos were analyzed.

The embryos used in the study were donated by couples who underwent IVF treatment, with frozen embryos remaining in storage; however, most were donated by couples who completed their family and wanted their surplus embryos to be used for research. The study was conducted under a rigorous regulatory licensing and research license from the Human Fertilization and Embryology Authority (HFEA), the independent UK Government regulator that oversees the treatment and research of infertility.
