It has been reported that erythropoietin (EPO) is currently being studied as a potential agent for neural repair. However, much evidence has confirmed that EPO treatment can induce systemic adverse effects in the clinical fields, including coronary stent thrombosis and deep vein thrombosis. Herein, a derivative of EPO without any hematopoietic activities, which is named carbamylated erythropoietin (CEPO), has been synthesized and investigated for its effects on peripheral neural repair both in vitro and in vivo. The in vitro experimental results demonstrated that CEPO enhanced Schwann cell viability, proliferation, migration, and nerve growth factor (NGF) expression, while the optimal concentration of CEPO was found to be 25 \u03bcg\/mL. The in vivo observations at 21 days post-injection indicated that the CEPO group exhibited a significant functional improvement in the sciatic nerve injury model, guiding regrowing axons across the injury site. Thus, CEPO serves as a promising candidate or adjunctive strategy for peripheral nerve injuries, demonstrating promising clinical applications and potential for enhancing Schwann cell viability, proliferation, and migration, as well as anticipated nerve axon development.<\/jats:p>","DOI":"10.3390\/ijms27104434","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T14:40:31Z","timestamp":1779115231000},"page":"4434","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Insights into the Effects of Carbamylated Erythropoietin on Schwann Cells in Peripheral Nerve Injury"],"prefix":"10.3390","volume":"27","author":[{"given":"Zhenzhen","family":"Wu","sequence":"first","affiliation":[{"name":"Oral and Maxillofacial Surgery, Faculty of Dentistry, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting Chak","family":"Lam","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Faculty of Dentistry, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4739-4938","authenticated-orcid":false,"given":"Shanthini","family":"Kalimuthu","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Faculty of Dentistry, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6670-6570","authenticated-orcid":false,"given":"Yiu Yan","family":"Leung","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Faculty of Dentistry, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"243","DOI":"10.5435\/00124635-200007000-00005","article-title":"Peripheral nerve injury and repair","volume":"8","author":"Lee","year":"2000","journal-title":"J.
