Redefining the Embryo: Scientists Call for a New Definition

Scientists are calling for a redefinition of the human embryo to include embryo models, which are structures made from stem cells that resemble early embryo development. These models raise ethical concerns as they do not meet current definitions of embryos and are not covered by regulations governing embryo research. The proposed redefinition would include embryo models if they have the potential to develop into a fetus. This would allow for more accurate and inclusive discussions within the scientific community. However, some researchers argue that it may be too soon to formalize such distinctions as embryo models are still in a rudimentary stage and face technical obstacles.
