Latar Belakang: Luka bakar memerlukan alternatif terapi selain silversulfadiazin SSD karena bersifat sitotoksik. Conditioned medium dari kultur selpunca mesenkimal asal jaringan lemak ADSC-CM disingkat CM kaya akansejumlah sitokin, vascular endothelial growth factor VEGF dan epidermalgrowth factor EGF yang berperan dalam re-epitelisasi. Proses ini didominasioleh migrasi, proliferasi dan diferensiasi keratinosit. Protein K19 merupakanpenanda sel progenitor keratinosit. ADSC-CM diharapkan mampu menjadialternatif SSD dalam terapi luka bakar.Metode: Penelitian dilakukan pada tikus model luka bakar Sprague dawley empat luka per ekor yaitu kontrol K , CM, medium complete MC dan SSDyang diberikan secara topikal. Penutupan luka secara makroskopis diukurmenggunakan visitrak digital pada hari ke-6, 12, 18 dan 24. Re-epitelisasi,ekspresi dan distribusi K19 diamati dengan pewarnaan hematoksilin-eosin danimunohistokimia.Hasil: Luas luka makroskopis menunjukkan bahwa kelompok CM mengalamipengurangan luas paling cepat, berbeda bermakna dengan kelompok K dan tidakbermakna dengan kelompok SSD. Hal tersebut sebanding dengan ekspresi K19pada epidermis. Secara mikroskopis, re-epitelisasi dimulai dari tepi luka,kelompok CM paling efektif daripada K, MC dan SSD.Kesimpulan: Penelitian ini menunjukkan bahwa CM paling efektif untuk reepitelisasidan ekspresi K19 sebagai progenitor sel keratinosit Aplikasi CMtopikal berpotensi sebagai alternatif terapi pada penyembuhan luka bakar.Kata kunci: Luka bakar, Mesenchymal Conditioned Medium, Keratin 19 K19 ,Re-epitelialisasi, Penutupan Luka.
Background Burns require alternative therapies other than silver sulfadiazine SSD for cytotoxic. Conditioned medium from adpose derived stem cell ADSCCMabbreviated CM is rich in a number of cytokines, vascular endothelialgrowth factor VEGF and epidermal growth factor EGF , which play a role inre epithelialization. This process is dominated by migration, proliferation anddifferentiation of keratinocytes. K19 protein is a marker of keratinocyteprogenitor cells. ADSC CM is expected to be an alternative SSD in the treatmentof burns.Methods The study was conducted on rats models of burns Sprague dawley four wounds per animal, control K , CM, complete medium MC and the SSD isadministered topically. Macroscopic wound closure was measured using a digitalvisitrak on days 6, 12, 18 and 24. Re epithelialization, and distribution K19expression was observed by hematoxylin eosin staining andimmunohistochemistry.Results As a macroscopic indicates that the CM group were reduced of thefastest wide, a significant difference with the group K, meaningless with SSD.This is comparable with the expression of K19 in the epidermis. Microscopically,re epithelialization starts from the edge of the wound, the group CM mosteffectively than K, MC and SSD.Conclusion This study shows that the most effective CM to re epithelializationand K19 expression as keratinocyte progenitor cells CM topical applicationpotential as an alternative therapy in the healing of burns. |
