The legislator's position in relation to research perspectives (concerningxenografts and constitution of stem cell banks)

Analysis of the legislation concerning xenotransplantation and constitution of stem cell banks reveals an absence of status common to embryos and anim als. They do not have any legal status, they are not assimilated to objects , but benefit from protective measures. Xenotransplantation is regulated by a set of rules, while embryo research i s currently prohibited in France, but is regulated in other countries. Bioethical legislation raises difficulties related to the early stage of it s development and its perverse effects. The consultation process prior to d efining legislation must take into account the international dimension and the necessary progress of scientific research.
