This research examined the topical wound healing efficacy of sepia ink extract (SIE) and SIE- Nanoparticle-loaded phytosome (SIE-NP) in a murine model of excisional wound healing. Mice were divided into five groups, all groups were anesthetized, and excisional skin wounds were established using a biopsy punch, except the control group. Both SIE and SIE-NP significantly improved the wound healing rate; nevertheless, the effect of SIE-NP was more pronounced. Treatment with SIE and SIE-NP accelerated the wound healing process by mitigating oxidative stress, evidenced by a reduction in malondialdehyde levels and an enhancement in antioxidants levels, including catalase and glutathione. SIE and SIE-NP attenuated oxidative stress-induced DNA fragmentation in wound tissue. Additionally, they reduced the levels of inflammatory markers, such as TNF-\u03b1 and IL-6, myeloperoxidase activity, and the infiltration of inflammatory cells in the skin tissue. Furthermore, SIE and SIE-NP reduced histopathological abnormalities and concentration of fragmented DNA and elevated nitric oxide levels and collagen content. Moreover, SIE and SIE-NP decreased apoptosis by lowering caspase 3 expression. The data indicate that SIE and SIE-NP expedited wound healing via their antioxidant, anti-inflammatory, and anti-apoptotic characteristics.<\/jats:p>","DOI":"10.1177\/15347346261448965","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T12:35:50Z","timestamp":1778848550000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Topical Application of Sepia Ink Extract-Loaded Phytosome on Mouse Skin Injury Accelerates Wound Healing: A Histopathological, Immunohistochemical, and Biochemical Study"],"prefix":"10.1177","author":[{"given":"Islam Ahmed","family":"Abdelmawgood","sequence":"first","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatma","family":"Alshakmak","sequence":"additional","affiliation":[{"name":"Lab Management Department, Faculty of Biomedical Sciences, Benghazi University, Benghazi, Libya"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2917-2423","authenticated-orcid":false,"given":"Hader I.","family":"Sakr","sequence":"additional","affiliation":[{"name":"Cairo University"},{"name":"Batterjee Medical College"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tarek","family":"Atia","sequence":"additional","affiliation":[{"name":"Department of Medical Laboratory Sciences, College of Applied Medical Sciences, Prince Sattam Bin Abdulaziz University in Al-Kharj, Al-Kharj, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayman Saber","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed W.","family":"El-Basyouni","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mazen Ashraf","family":"Abdelaziz","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed M.","family":"Rochdi","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shady H.","family":"Mahmoud","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin M.","family":"Mikhail","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Verina S.","family":"Shehata","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica M.","family":"Rezkalla","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nada M.","family":"Ali","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3454-7487","authenticated-orcid":false,"given":"Mariam A.","family":"Alsayed","sequence":"additional","affiliation":[{"name":"Batterjee Medical College"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hajar A.","family":"Mutawalli","sequence":"additional","affiliation":[{"name":"Batterjee Medical College"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jakleen Z.","family":"Abujamai","sequence":"additional","affiliation":[{"name":"Batterjee Medical College"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adel","family":"Alghamdi","sequence":"additional","affiliation":[{"name":"Vice Dean, Vision Medical College, Jeddah, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wafaa M.A.","family":"Abdulrahman","sequence":"additional","affiliation":[{"name":"Batterjee Medical College"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neamat","family":"Mahmoud Abd Elgilil","sequence":"additional","affiliation":[{"name":"Cairo University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"Ozgok Kangal MK Kopitnik NL.
