[The legislator's position regarding research perspectives (concerning xenografts and the development 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 animals. 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 is currently prohibited in France, but is regulated in other countries. Bioethical legislation raises difficulties related to the early stage of its development and its perverse effects. The consultation process prior to defining legislation must take into account the international dimension and the necessary progress of scientific research.
