Scientometric analysis of evolution in sex-specific MSC therapy for cardiovascular diseases

Mesenchymal stem cell (MSC) therapy for cardiovascular diseases has shown promise; however, sex-specific differences remain understudied. This scientometric analysis provides the first comprehensive overview of sex-specific differences in mesenchymal stem cell (MSC) therapy for cardiovascular diseases, spanning from 1947 to 2024.

We analyzed 61,029 publications using advanced bibliometric tools to identify research hotspots, publication trends, and collaborative networks.

A significant shift in research focus has been observed in the field of mesenchymal stem cell (MSC) therapy for cardiovascular diseases, transitioning from broad cardiovascular concepts in the 20th century to specialized sex-specific considerations in the 21st century. Furthermore, in the 21st-century research landscape, the formation of two distinct clusters for "male" and "female" in VOSviewer-generated network visualizations is highly important, emphasizing the growing recognition of sex-specific differences in MSC therapy responses and outcomes. This shift was accompanied by a marked increase in terminology related to sex-specific differences, with keywords like "genetic association" and "body mass index" forming distinct clusters in recent years.

This analysis underscores the critical need for sex-specific considerations in MSC therapy for cardiovascular disease. The emergence of distinct male and female clusters in research networks emphasizes the importance of tailoring approaches based on sex differences. Key areas identified for future investigation include the role of epigenetics in mediating sex-specific effects and the potential of sex-matched MSC-derived exosomes. These findings pave the way for more effective and personalized approaches in cardiovascular regenerative medicine, potentially leading to improved outcomes through sex-specific therapeutic strategies.
