Abstract:Objective Through the study of the American gene editing supervision system, this paper provides reference for improving the scientific and operational effectiveness of gene editing ,and improving the supervision system in China. Method: The regulatory system of gene editing in the United States is deeply explored from three aspects: The top-level design, The operation mechanism and The practical experience. Result America"s regulatory regime for gene-editing research is based on scientific compliance,be able to timely adjust according to the needs of technical development,Particular pay attention to the openness and transparency of the regulatory process,and the principles of regulation are clear, the boundaries clear and the details in place. Conclusion China can learn from the regulatory experience of the United States and accelerate the legislative process of gene editing, formulating a scientific, comprehensive, long-term and cooperative regulatory mechanism to promote the healthy development of gene editing technology in China.
