Background:
Heterotopic ossification is a complication in the late stage of ankylosing spondylitis (AS), and involves abnormal osteogenesis by mesenchymal stem cells (MSC). Research activity in this area has been rapidly expanding, but there is a lack of bibliometric studies that summarize the progresses.
Methods:
We searched the Web of Science (WoS) for articles pertaining to the role of MSCs in heterotopic ossification in AS from the database inception to December 2022 and visualized the countries, authors, institutions, references, and keywords using CiteSpace 6.1.R6 and VOSViewer.
Results:
A total of 127 publications from 188 institutions were identified, with a trend for increasing number of articles per year. China published the largest number of literature, followed by the United States and France. There were 47 core authors. The most recent research in this area mainly focused on "osteogenic differentiation", "gene expression", "inflammation", "TNF-α" and "bone formation". Current research can be broadly summarized into two topics: abnormalities in the inflammatory microenvironment and abnormalities in the MSCs. Aberrant expression of a variety of surface proteins in MSCs predisposes these cells to undergo osteogenic differentiation, and pro-inflammatory cytokines in the inflammatory milieu stimulate osteogenic differentiation of MSCs.
Conclusion:
MSCs in heterotopic ossification in AS is a relatively new area of research. Research activities primarily consist abnormalities in the inflammatory microenvironment and abnormalities in the MSCs.
