Abstract: BACKGROUND: As novel cell-free nanocarriers, animal- and human-derived exosomes have become research hotspots in regenerative medicine, thanks to their low immunogenicity and dual regulatory advantages in promoting vascularization and osteogenesis. However, there is currently a lack of systematic bibliometric analysis regarding the research status and evolutionary trends in this field.
OBJECTIVE: To perform a visualization analysis of relevant literature concerning the application of animal/human-derived exosomes in bone tissue repair, exploring research hotspots and current status to provide a reference for future studies.
METHODS: Literature related to animal/human-derived exosomes in the field of bone tissue repair published between January 1, 2015, and November 27, 2025, was retrieved from the Web of Science Core Collection and the China National Knowledge Infrastructure. Statistical and visualization analyses were conducted using Microsoft Office Excel 2019, CiteSpace 6.4.R1, VOSviewer 1.6.20, and the R-Bibliometrix package.
RESULTS AND CONCLUSION: (1) A total of 403 English publications from Web of Science Core Collection and 152 Chinese publications from China National Knowledge Infrastructure were included. The overall volume of publications shows an upward trend, with English literature growing at a faster rate. (2) In the Web of Science Core Collection database, China ranks first in the number of publications (303 articles), while the United States exhibits the strongest international collaboration capacity, with a betweenness centrality of 0.71. The most prolific institution and journal are Shanghai Jiao Tong University and the Journal of Nanobiotechnology, respectively. (3) Among the analyzed literature, Furuta (2016) has the highest citation count (360). Within the references cited by these documents, Kalluri (2020) is the most frequently cited (70 times). (4) Keyword co-occurrence and evolution analysis show that “exosomes” and “bone regeneration” are core hotspots. Research themes have evolved from early basic mechanisms such as “inflammation” and “fracture healing” toward application levels like “immunomodulation” and “angiogenesis.” “Hydrogels” are emerging as a key carrier linking microscopic mechanisms to macroscopic therapy. (5) Future research will shift from single-mechanism validation to engineered product transformation, focusing on the regulation of the immune microenvironment and the coupling mechanism of vascular-bone regeneration. Additionally, milk-derived exosomes are expected to become a significant new direction for low-cost clinical translation due to their high yield, low cost, and ease of administration.
