Abstract
AIM: There have been increased interests in the use of stems cells in the research of osteoarthritis (OA). The present study aimed to investigate the global status and trends in this field. METHOD: Publications related to stem cells search in OA from 1994 to 2017 were retrieved from the Science Citation Index-Expanded Web of Science. The source data were studied and indexed using a bibliometric methodology. For visualized study, VOS viewer software was used to conduct bibliographic coupling, co-authorship, co-citation and co-occurrence analysis and to analyze the publication trends in stem cells for OA research. RESULT: A total of 1933 articles were included. The relative research interests and number of publications were globally increasing per year. The USA made the highest contributions to the global research with the most citations and the highest H-index. The journal Osteoarthritis and Cartilage had the highest publication number. The Tokyo Medical and Dental University, University of Pittsburgh and Shanghai Jiaotong University were the most contributive institutions. Studies could be divided into four clusters: mechanism study, animal study, clinical trials and tissue engineering. The clinical studies were predicted to be the next popular topic in this field. CONCLUSION: The number of publications about stem cells for OA would be increasing based on the current global trends. The USA was the largest contributor in this field. Most efforts could be put into clinical studies involving mesenchymal stem cells for OA, which may be the next hot spots in OA and stem cells research.
