From the moment sperm fuses with an egg, human embryo development involves a string of complex and little understood processes. What happens during human embryo development, particularly in the crucial first month, remains largely unknown. However, 14 days is an important milestone because it is when permitted lab research on cultured human embryos routinely ends. He said, in the future, it might be possible to go as far as 40 days with human embryo models. Some in the field envision a “tipping point” wherein human embryo models might be afforded some protection like those surrounding human embryos, as scientific advances diminish the differences between the embryo models and their real-life counterparts.
