摘要
背景:非编码RNA作为一类不编码蛋白质的RNA分子,在细胞调控中发挥关键作用。同时,间充质干细胞具有多向分化潜能,对组织修复和再生至关重要。近年来,研究者们对非编码RNA在调控间充质干细胞功能中的作用展开了深入探讨。目的:通过文献计量学分析方法系统地了解非编码RNA与间充质干细胞相关研究的发展趋势与关键领域。方法:从Web of Science核心合集1990年至今的科学引文索引扩展获取非编码RNA与间充质干细胞相关研究的文献数据,运用VOSviewer和Cite Space计量学软件对年份、国家或地区、研究机构、被引文献和关键词进行发文量、聚类、被引频次、突增性和中介中心性进行分析,揭示该研究领域的知识基础及前沿热点。结果与结论:(1)最终纳入5348篇文献,发表在1997-2021年,相关文献呈现明显的增长趋势,尽管在2022年略有减少,其发文量仍保持较高水平,中国在该领域的研究中占据主导地位,其中上海交通大学为最活跃的机构。(2)对被引文献分析发现,高突增性、高中介中心性、高被引的文献主要与微小RNA、细胞外囊泡和骨代谢等内容相关,这些文献构成了非编码RNA与间充质干细胞研究领域的重要知识基础。(3)对关键词进行突增性分析发现,至今保持高突增性的关键词包括外泌体、环状RNA、细胞外囊泡和损伤。(4)对关键词进行聚类演变分析,发文量仍保持增长趋势的关键词聚类包括:肿瘤微环境、骨关节炎、氧化应激和细胞外囊泡,这些关键词反映了目前以及未来该领域的研究热点。(5)文章结果不仅展示了非编码RNA与间充质干细胞研究领域的研究态势,更重要的是有望为研究人员提供潜在的方向和启示。
BACKGROUND:Non-coding RNA,as a class of RNA molecules that do not encode proteins,plays a crucial role in cellular regulation.Simultaneously,mesenchymal stem cells possess multipotent differentiation capabilities,making them vital for tissue repair and regeneration.In recent years,researchers have extensively explored the role of non-coding RNA in regulating the functions of mesenchymal stem cells.OBJECTIVE:To systematically understand the trends and key areas of research related to non-coding RNA and mesenchymal stem cells through bibliometric analysis.METHODS:Literature data on non-coding RNA and mesenchymal stem cell-related research were retrieved from the Science Citation Index Expanded in the Web of Science Core Collection from 1990 to the present.The literature data were analyzed using bibliometric tools such as VOSviewer and CiteSpace,focusing on publication output,clustering,citation frequency,burstiness,and intermediary centrality with respect to years,countries or regions,research institutions,cited references,and keywords.This analysis aimed to reveal the knowledge base and emerging hotspots in the research field.RESULTS AND CONCLUSION:(1)This study included a total of 5348 articles for analysis,showing a significant growth trend in relevant literature from 1997 to 2021.Although there was a slight decrease in 2022,the publication output remained at a high level.China dominated the research in this field,with Shanghai Jiao Tong University being the most active contributor.(2)Analysis of cited references revealed that highly bursty,intermediary,and cited articles were mainly related to topics such as microRNA,extracellular vesicles,and bone metabolism.These articles constitute an important knowledge base for research on non-coding RNA and mesenchymal stem cells.(3)Burstiness analysis of keywords identified persistent bursts in keywords such as exosomes,circular RNA,extracellular vesicles,and injury.(4)Cluster evolution analysis of keywords with continuous growth in publication output included clusters r
