Hotspots and trends in stem cell therapy for liver fibrosis and cirrhosis: A bibliometric analysis.

Background: Liver fibrosis and cirrhosis are global medical challenges that require safe and effective treatments. In the past two decades, there has been a surge in research on stem cell therapy for liver fibrosis and cirrhosis. This study aimed to conduct a comprehensive analysis of the research hotspots and trends in this field through bibliometrics.

Aim: To conduct a bibliometric analysis on hotspots and trends in stem cell therapy for treatment of liver fibrosis and cirrhosis.

Methods: Publications on stem cell therapy for liver fibrosis and cirrhosis were retrieved from the Web of Science Core Collection database. The distribution and collaboration among literature, authors, countries, and institutions were analyzed visually using Excel, CiteSpace, Bibliometrix R-package, VOSviewer and Pajek software. Additionally, an investigation of keywords, burst keywords, and clusters was conducted.

Results: As of September 20, 2024, a total of 1935 documents were retrieved dating from 2004 to 2024, with 1186 strongly relevant publications obtained after screening. China, the United States, and Japan were the major contributors in this field. Cairo University, Zhejiang University and Yamaguchi University were the major institution in this field. The journal Stem Cell Research & Therapy published the most papers. There were 686 authors, with Shuji Terai, Isao Sakaida, Soon Koo Baik, and Lanjuan Li publishing the most papers. The research focused on alcoholic cirrhosis and nonalcoholic fatty liver disease. The emerging areas of interest were extracellular vesicles, exosomes, and their enriched microRNAs. The field is experiencing rapid growth due to the changing research trends and increasing literature.

Conclusion: These findings provide a thorough overview of stem cell therapy in the field of liver fibrosis and cirrhosis.
