基于2018-2022年国家自然科学基金结题项目分析干细胞研究现状

背景:目前大多数研究从国家自然科学基金资助论文和项目申请角度出发,对干细胞某一方面进行深入分析,或者验证某种评价方法,缺乏对干细胞领域国家自然科学基金已结题项目的全面分析.目的:了解2018-2022年干细胞领域国家自然科学基金结题项目资助情况及研究热点,为后续研究提供参考.方法:以"干细胞"为检索词,检索国家自然科学基金大数据知识管理服务门户等数据库,提取结题项目信息,对关键词、依托单位和地区等字段进行清洗和归并,并用Excel、Echarts、VOSviewer等软件进行词频统计、聚类分析和可视化展现.结果与结论:国家自然科学基金干细胞结题项目展现了多学科交叉融合的显著特点,不仅涵盖医学和生命科学,还涉及化学、信息科学、工程和材料学、地球科学、数理科学等多个学科,为干细胞产业的发展带来了革命性进步.关键词聚类分析显示,中国对干细胞的资助主要集中在间充质干细胞、肿瘤干细胞、胚胎干细胞、神经干细胞和造血干细胞等领域.通过对比,中美英三国的基金资助各有侧重,反映了各国在干细胞领域的不同发展方向,并为国际合作提供了广阔空间.近5年内,尽管结题数量保持稳定,但结题金额稍有下降,表明中国在干细胞领域的资金投入相对不足.因此,建议加强国家自然科学基金在此领域的投入,并引导更多社会资本参与,形成多元化投入格局,以促进干细胞产业的快速发展.
Analyzing current status of stem cell research based on National Natural Science Foundation of China's completed projects from 2018 to 2022
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.
