Exploring the landscape of stem cell extracellular vesicle research for angiogenesis: A bibliometric analysis from 2003 to 2023

Abstract

AbstractBackgroundExosomes and other secretory membrane vesicles are collectively referred to as extracellular vesicles (EVs). Relevant data indicate that stem cell‐derived extracellular vesicles (SC‐EVs) play a critical role in angiogenesis by transmitting crucial information such as proteins, second messengers, and genetic material between cells. Therefore, this study aimed to map current trends on SC‐EVs for angiogenesis and provide directions for future research to advance this important field.MethodsWe conducted a thorough search for relevant studies on SC‐EVs for angiogenesis from 2003 to 2023 using the Web of Science database. Subsequently, we used VOSviewer and CiteSpace to analyze the collected data.ResultsA total of 2359 relevant publications, which included original articles and reviews, related to the role of SC‐EVs in angiogenesis were screened in this study based on the search strategy. China and the United States were leading in this field, with China having a higher output in terms of publications and citations (1172, 43681). Also, the top five universities were located in China, with Shanghai Jiao Tong University having the highest output. Stem Cell Research & Therapy and International Journal of Molecular Sciences, are prominent platforms for researchers in this field to share their findings and advancements, and they had most of published studies on SC‐EVs for angiogenesis. The results derived from the cluster analysis suggested that future investigations should predominantly prioritize studying the involvement of SC‐EVs in angiogenesis across various diseases, with a specific emphasis on skin wound healing.ConclusionIn this comprehensive review, global trends in SC‐EVs for angiogenesis were analyzed. The analysis of journals, institutions, references, and keywords could assist researchers in deciding on the direction of research. The role of SC‐EVs in promoting angiogenesis during wound healing and repair represents an emerging research focus.
