 The ‘Hinxton Group’ met recently for the first time, in Cambridge, and published a consensus statement calling for a ‘flexible’ regulatory framework, which can simultaneously accommodate rapid scientific advance and at the same time accommodate the diversity of international approaches towards stem cell science.It also recommends that, in countries which oppose embryonic stem cell research, scientists should be free to pursue their research elsewhere.In light of the controversy surrounding Hwang Woo-Suk, the Hinxton Group has additionally recommended a number of measures intended to prevent fraud in stem cell research.
