Research using human embryos and embryoids has expanded in recent years due to technological advances. Surveying laws and guidelines among the top research and development (R&D) investing nations highlights existing barriers to expanding this area of research. Of the 22 nations surveyed, we found 12 countries with a 14-day limit, one with a seven-day limit, five with prohibitions and four without national laws or guidelines that limit or prohibit human embryo research. Sixteen national laws or guidelines define an embryo or related entities, with five nations limiting human embryoid research. Other laws are ambiguous in relation to embryoid research, leave unanswered questions regarding what research is permitted or restricted and need additional clarity for researchers.
近年来，由于技术的进步，利用人类胚胎和类胚胎进行的研究不断增加。调查顶尖研发投资国家的法律和指导方针，突出了扩大这一研究领域的现有障碍。在接受调查的 22 个国家中，我们发现有 12 个国家对人类胚胎的研究有 14 天的限制，一个国家有 7 天的限制，5 个国家禁止研究，4 个国家没有限制或禁止人类胚胎研究的国家法律或指导方针。16 个国家的法律或指导方针定义了胚胎或相关实体，其中 5 个国家限制人类类胚胎的研究。其他法律在类胚胎研究方面含糊不清，对于允许或限制哪些研究没有明确的答案，也需要为研究人员提供更多的明确性。
