Abstract (original English)

Stem cells have been confirmed to be involved in the occurrence and development of diabetic retinopathy; however, the underlying mechanisms remain unclear. In this study, we used Citespace software to visually analyze 552 articles exploring the stem cell-based treatment of diabetic retinopathy over the past 20 years, which were included in the Web of Science Core Collection. We found the following: (1) a co-citation analysis of the references cited by all 552 articles indicated 15 clusters. In cluster #0, representing the stem cell field, some highly cited landmark studies emerged between 2009-2013. For example, endothelial progenitor cells and diabetic retinopathy gradually received the full attention of scholars, in terms of their relationship and therapeutic prospects. Some researchers also verified the potential of adipose-derived stem cells to differentiate into stable retinal perivascular cells, using a variety of animal models of retinal vascular disease. All of these achievements provided references for the subsequent stem cell research. (2) An analysis of popular keywords among the 552 articles revealed that, during the past 20 years, a relative increase in basic research articles examining stem cells and endothelial progenitor cells for the treatment of diabetic retinopathy was observed. The contents of these articles primarily involved the expression of vascular endo
