However, this method has limitations and novel alternatives are needed. Here, the efficacy of acellular nanostructured fibrin-agarose hydrogel-based substitutes (NFAH) in the repair of scleral defects in rabbits was studied. For this, scleral defects of 5-mm diameter were made on 18 adult-male New Zealand rabbits and repaired with acellular NFAH, NFAH crosslinked with genipin (NFAH-GP) or glutaraldehyde (NFAH-GA), allogeneic scleral grafts as control (C-CTR) or not repaired (negative control N-CTR) (n=3 each). Macroscopic and histological analyses were performed after 40-days. Macroscopy confirmed the repair of all defects in a comparable manner than the C-CTR. Histology showed no degradation nor integration in C-CTR while NFAH-GP and NFAH-GA biomaterials were encapsulated by connective and inflammatory tissues with partial biodegradation. The NFAH were fully biodegraded and replaced by a loose connective tissue and sclera covering the defects. This in vivo study demonstrated that the NFAH are a promising biocompatible and pro-regenerative alternative to the use of allogeneic cadaveric grafts. However, large defects and long-term studies are needed to demonstrate the potential clinical usefulness of these substitutes.}, organization = {Junta de Andalucía CS PI-0400-2016}, organization = {Ministerio de Economía y Competitividad (Instituto de Salud Carlos III) FIS PI17/391}, organization = {“Fondo Europeo de Desarrollo Regional (FEDER),” European Union}, publisher = {Elsevier}, keywords = {Escleral surgical repair}, keywords = {Hydrogels}, keywords = {Crosslinking}, keywords = {Tissue engineering}, keywords = {Eyeball}, keywords = {Fibrin/agarose}, keywords = {Histology}, title = {Scleral surgical repair through the use of nanostructured fibrin/agarose-based films in rabbits.}, doi = {10.1016/j.exer.2019.107717}, author = {Carriel Araya, Víctor and Vizcaíno López, Gerson and Chato Astrain, Jesús and Durand Herrera, Daniel and Alaminos Mingorance, Miguel and Campos Muñoz, Antonio Jesús and Sánchez-Montesinos García, Indalecio and Campos Sánchez, Fernando}, }
