Regenerative properties of recombinant human erythropoetin in wound healing

Erythropoietin is the main stimulator of erythropoiesis, but erythropoietin also has non-hematopoietic effects. The recent data show the positive effects of erythropoietin on tissue regeneration. This review highlights the pathophysiological mechanisms of erythropoietin at different stages of tissue regeneration, and possible clinical applications in wound healing. Aim. Study of the world experience of using erythropoietin for the treatment of experimental wounds and the experience of clinical use for the treatment of patients with chronic wounds. Material and methods. The literature was searched in the databases: Pubmed, EMBASE and Google Scholar using the keywords: "Erythropoietin", "EPO", "wounds", "wound treatment", "VEGF", "re-epithelialization", "skin". The search depth was 20 years. When compiling a search strategy, the use of the title of articles, abstracts, as well as conference materials in English, Russian, Kazakh languages was used. Experimental original articles, narrative reviews were included in this review. Results and discussion. To date, there is a sufficient amount of experimental data confirming the effectiveness of EPO on the pathomorphological processes of skin wound healing, but it is still impossible to determine a single mechanism or cellular function that could be responsible for the ability of tissue regeneration mediated by EPO. Conclusion. Research into the ability of erythropoietin to improve tissue regeneration may lead to new insights into this growth hormone for its regular clinical use in patients. Key words: EPO, wound healing, VEGF, reepithelization, skin.
