In this study, we identified and evaluated VEGF Mimetic Peptide3 (VMP3), a novel synthetic peptide developed as a potential VEGFR\u20102\/VEGF\u2010A modulator. VMP3 was generated using an AI\u2010assisted peptide design framework incorporating long short\u2010term memory (LSTM) networks, which enabled learning of sequence\u2010level patterns within known VEGF agonist peptides and assisted the motif\u2010guided and structure\u2010informed design of new candidates. Molecular dynamics simulations suggested a stable interaction profile between VMP3 and VEGFR2, supporting the feasibility of receptor engagement. Experimental validation was performed using in vitro, ex vivo, and in vivo methods. In vitro functional assays showed that VMP3 promoted endothelial cell proliferation, migration, and invasion in a manner similar to that of native VEGF. Ex vivo aortic ring assays supported these findings, demonstrating micro vessel sprouting following VMP3 treatment. An in vivo Matrigel plug assay in C57BL\/6J mice revealed increased neovascularization following VMP3 treatment, as confirmed by histological and immunohistochemical analyses (H&amp;E and CD31 staining). In addition, in a diabetic mouse wound healing model, VMP3 significantly accelerated wound closure, and tissue\u2010level analysis of wound sites confirmed enhanced re\u2010epithelialization and neovascularization, as evidenced by Masson's trichrome, Picrosirius Red, H&amp;E, and CD31 staining. Collectively, these results suggested that VMP3 functions in a manner similar to that of VEGF, promoting angiogenesis.<\/jats:p>","DOI":"10.1002\/pro.70529","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T04:15:17Z","timestamp":1773375317000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>AI<\/scp>\n
