Abstract  

Objective: Compare the development status and trends of mesenchymal stem cells (MSCs) in basic research, patent application and clinical trial registration between China and the US. Find out the main characteristics of MSCs research in these two countries and provide suggestions for Chinese MSCs development. Methods: The paper data in SCI database, the patent data in DII database and the clinical trial data in Clinical Trials database are retrieved. The quantitative analysis is carried out by Excel and DDA. SWOT analysis is used to discuss the advantages and disadvantages, opportunities and threats of Chinese MSCs development. Results: Although China started late on MSCs research, it has developed rapidly in recent years. The number of papers since 2014 and patent applications in 2016 exceeds that of the United States, and the number of clinical trials has reached more than 200. China has advantages in the research fields of osteoporosis and spinal cord injury and some clinical trials such as endocrine system diseases and autoimmune diseases. However, there is still room for improvement in the study of MSCs in China. Conclusion: China should give full play to its existing advantages and strengthen the strategic layout; attach importance to the enterprise-led new drug development path; make efforts to enhance its international competitiveness and influence; increase capital investment and support of industrial policies and improve the regulatory mechanism and evaluation system.
