Figures 9B, 10B are the cluster plot and timeline chart, respectively, which show that nine subject phrases were grouped using the CiteSpace software: microRNA, cancer therapy, personalized medicine, sarcoma, canine leishmaniasis, osteoblast, noncoding RNA, IL-6, cartilage cells in vitro, and flow cytometry. The research hotspot gradually shifted toward miRNAs and noncoding RNA, as illustrated in Figure 10B. Here, IL6 is linked to sarcoma.
