Abstract
We consider the scientific evidence that research on in-vitro development of embryos beyond 14 days is necessary. We then examine potential new developments in the use of stem cells to make embryoids or synthetic human entities with embryo-like features, and consider whether they also require legal control. Next, we consider the arguments advanced against extending the 14-day period during which research on human embryos is currently permitted, and find none of them to be convincing. We end by proposing a new objective limit that could serve as a mechanism for regulating the use of embryos for research .
摘要
我们认为有科学证据表明，对超过14天的胚胎进行体外发育研究是必要的。然后，我们研究了利用干细胞制造类胚胎或具有胚胎样特征的合成人类实体方面潜在的新进展，并考虑它们是否也需要法律管控。接下来，我们考量了针对延长目前允许进行人类胚胎研究的14天期限所提出的论据，发现这些论据都不具有说服力。最后，我们提出了一个新的客观限制，它可以作为一种管控用于研究的胚胎的使用的机制。
