- Abstract: BACKGROUND:At present,most research focuses on in-depth analysis of a certain aspect of stem cells from the perspective of papers and project applications funded by the National Natural Science Foundation of China,or verifies certain evaluation methods,lacking a comprehensive analysis of the completed projects of the National Natural Science Foundation of China in the field of stem cells. OBJECTIVE:To understand the funding status and research hotspots of National Natural Science Foundation of China projects in the field of stem cells from 2018 to 2022,providing a reference for subsequent research. METHODS:Using"stem cells"as the search terms,databases were searched such as Big Data Knowledge Management Service Portal of the National Natural Science Foundation of China to extract project information,clean and merge keywords,institutions,supporting units and regions.Software such as Excel,Echarts,and VOSviewer was used to perform word frequency statistics,cluster analysis,and visualization. RESULTS AND CONCLUSION:The National Natural Science Foundation of China's Stem Cell Project has demonstrated significant characteristics of interdisciplinary integration,covering not only medicine and life sciences,but also multiple disciplines such as chemistry,information science,engineering and materials science,earth science,and mathematical science,bringing revolutionary progress to the development of the stem cell industry.Keyword clustering analysis shows that China's funding for stem cells mainly focuses on areas such as mesenchymal stem cells,tumor stem cells,embryonic stem cells,neural stem cells,and hematopoietic stem cells.By comparison,the funding of China,the United States,and the United Kingdom each has their own emphasis,reflecting the different development directions in the field of stem cells in each country and providing broad space for international cooperation.In the past five years,although the number of completed projects has remained stable,the amount of completed projects has slightly decreased,indicating that China's investment in the field of stem cells is relatively insufficient.Therefore,it is recommended to strengthen the investment of the National Natural Science Foundation in this field and guide more social capital to participate,forming a diversified investment pattern to promote the rapid development of the stem cell industry.
