This study aimed to explore the cellular composition of the laughing dove's cornea, focusing on telocytes\u2014a cell type previously unreported in avian corneas. This work represents the first demonstration of telocytes in the cornea of any bird species. We used hematoxylin and eosin (H&amp;E) staining to comprehensively visualize the corneal layers, while silver staining, methylene blue, toluidine blue staining, and immunofluorescence with telocyte\u2010specific markers (CD34, PDGFR\u03b1, and vimentin) were utilized to identify telocytes and confirm their distribution. The cornea of the laughing dove was shown to consist of five unique layers: the epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium. Telocytes were detected using silver, methylene blue, and toluidine blue stains as spindle\u2010shaped cells with branched extensions known as telopodes. Double immunofluorescence for PDGFR\u03b1 and CD34 confirmed the existence of telocytes across all corneal layers. In the epithelium, intraepithelial telocytes were sparsely distributed, possibly contributing to epithelial maintenance and cellular signaling. In Bowman's layer, telocytes were identified, likely supporting structural integrity and intercellular interactions. The stroma exhibited the highest abundance of telocytes, highlighting their critical role in extracellular matrix remodeling and cellular connectivity. In Descemet's membrane, telocytes likely contribute to the structural stability of this basement membrane, while in the endothelium, they appear to play roles in endothelial repair, fluid regulation, and signaling processes. Double immunofluorescence of vimentin and CD34 revealed distinct localization patterns. While CD34 identified telocytes in all corneal layers, vimentin expression was confined to the stroma, predominantly in the superficial region. Vimentin was specifically localized to telopodes, while CD34 was more evenly distributed, with strong expression in both the central bodies of telocytes and telopodes. The partial co\u2010expression of CD34 and vimentin suggests functional specialization within telocytes, with vimentin likely supporting telopode structure and long\u2010range signaling. Our findings underscore the critical role of telocytes in corneal structure and function, particularly their contributions to the laughing dove's adaptation to harsh environmental conditions. This study not only identifies telocytes in the avian cornea for the first time but also highlights their presence in all corneal layers, suggesting their broader functional roles in maintaining corneal homeostasis and resilience.<\/jats:p>","DOI":"10.1002\/jemt.24845","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T16:55:00Z","timestamp":1741712100000},"page":"2009-2024","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Novel Insights Into Telocyte Presence and Distribution in the Cornea of the Laughing Dove (<i>Spilopelia senegalensis<\/i>) Using Immunofluorescence Analysis"],"prefix":"10.1002","volume":"88","author":[{"given":"Ahmed M.","family":"Rashwan","sequence":"first","affiliation":[{"name":"Department of Anatomy and Embryology, Faculty of Veterinary Medicine Damanhour University  Damanhour Egypt"},{"name":"Laboratory of Life Science Frontiers, Center for iPS Cell Research and Application (CiRA) Kyoto University  Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hagar M.","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Department of Medical Laboratory Analysis, Faculty of Medical &amp; Health Sciences Liwa College  Abu Dhabi UAE"},{"name":"Department of Applied Medical Chemistry, Medical Research Institute Alexandria University  Alexandria Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samir A.
