Laboratory animal science(LAS)advances scientific understanding of the care and use of animals that play a key role in research supporting the development of biomedicine.LAS has developed quickly in China in recent decades,and this report provides an analysis of the current status of the countrys LAS policies and administration.National and provincial laws,regulations,guidelines,and standards apply to quality control and licensing,quarantine and infectious disease control,breeding and husbandry,transgenic animals,staffqualifications,animal welfare,and imports,exports,and transportation.Regulation and oversight of lab animal use are the responsibility of the national Ministry of Science and Technology,provincial departments of science and technology,and institutional animal care and use committees.We begin with an explanation of the rationale behind this paper and a brief history of policy-related activities and achievements.We then present various policies,discuss their implementation,and hypothesize about future policy developments.With the improvement of policies under an integrated,multitiered administration,the use of high-quality lab animals in Chinese scientific research is increasing and many more papers describing animal experiments performed in China are being published in international journals.
