Regulating embryo models in the UK.

Abstract

One of this century's most dramatic scientific developments is the reprogramming of stem cells in order to create self-organizing embryo-like entities, known as stem cell based embryo models (SCBEMs). The science is moving very quickly, but if, as increasingly appears to be the case, scientists are capable of creating entities that are effectively indistinguishable from sperm and egg derived embryos, important legal questions arise. In countries like the UK, where a strict regulatory regime applies to research on embryos, should this be extended to SCBEM research, or would a different regulatory response be appropriate? Drawing on the 1984 Warnock Report, the Human Fertilisation and Embryology Act 1990 and the latest guidelines from the International Society for Stem Cell Research, this article considers principles for the regulation of the creation and use of SCBEMs.
