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.

我们可以在这里做吗？对指导人类胚胎和胚胎研究的美国联邦和州政策的分析。

最近的技术进步帮助科学家了解早期人类发展。然而，科学家充分挖掘其潜力的能力与美国的国家和州级政策相冲突。2016 年，研究人员首次能够在培养物中培养长达 14 天的人类胚胎，但由于科学和法律限制而停止。其他研究人员已经在培养中使用干细胞来创建早期人类发育的有组织模型，称为胚胎或基于细胞的胚胎模型。在本文中，我们回顾了影响美国人类胚胎和胚胎研究的联邦和州法律。虽然联邦政策侧重于资金，但州法律通常与人类胚胎干细胞、流产、胎儿组织研究和生殖克隆有关。在有影响人类胚胎研究的法律的 29 个州中，只有 11 个州禁止它，没有一个州直接涉及胚胎，尽管有五个州限制了这项研究的各个方面。总体而言，这种复杂的情况表明，额外的国家指导将帮助科学家和公众驾驭这些有争议的研究领域，但是，考虑到过去缺乏决定胚胎研究政策的进展，这不太可能发生。
