Analysis of current trends in angiogenesis research for wound healing: A bibliometric study from 2013 to 2023

Background: Traumatic injuries, surgery, and chronic diseases lead to soft tissue wounds. Stimulating normal wound healing (WH) is important for tissue repair and restoration of homeostasis. Lack of angiogenesis impedes wound healing and is noted in chronic wounds. The goal of this investigation was to thoroughly assess the present state and patterns of investigations on angiogenesis in WH by the use of bibliometric analysis.

Methods: Studies examining angiogenesis and WH were sourced from the database of the Web of Science Core Collection. Only studies that fulfilled the inclusion criteria were chosen for the purpose of investigation. To analyze the publications included in this research, bibliometric and visual analysis techniques were applied utilizing tools like VOSviewer and CiteSpace.

Results: For the analysis, 11,558 papers were considered. The number of publications increased annually from 2013 to 2023. China, the USA, and South Korea were the top nations in this subject, accounting for 41.1 %, 19.4 %, and 5.8 % of published articles, respectively. The author and institution with the greatest number of publications were found to be Chang J and Shanghai Jiao Tong University. PLOS One had the greatest publication count among journals, whereas Biomaterials had the greatest number of citations and was often mentioned in co-citations. Angiogenesis-related biomedical engineering and tissue engineering were the topics that received the most research attention. Recent studies have focused on vascular endothelial growth factor and carboxymethyl chitosan as emerging areas of interest.

Conclusion: In this investigation, we compiled the features of publications and determined the most impactful nations, organizations, writers, periodicals, popular subjects, and patterns concerning the process of angiogenesis in the context of WH.
