Recent technological advances have helped scientists understand early human development. However, scientists’ ability to fully explore their potential comes in conflict with national and state-level policies in the USA. In 2016, for the first time, researchers were able to grow human embryos in culture up to 14 days but stopped because of scientific and legal limits. Other researchers have used stem cells in culture to create organized models of early human development, known as embryoids or cell-based embryo models. In this paper, we review federal and state laws that affect US human embryo and embryoid research. While federal policies focus on funding, state laws are often associated with human embryonic stem cells, abortion, fetal tissue research, and reproductive cloning. Of the 29 states with laws impacting human embryo research, only 11 states ban it, and none address embryoids directly, although five states limit aspects of this research. Overall, this complicated landscape suggests that additional national guidance would help scientists and the public navigate these controversial areas of research, however, it is unlikely to happen, considering the lack of past progress determining embryo research policy.
