T050SC combined with chitosan-activated (cPRP) was formulated as eye drops for application for severe DES. To evaluate the effects of cPRP and TOSCNFs on the repair of corneal injury, in vitro studies were conducted using Statens Seruminstitut rabbit corneal (SIRC) epithelial cells for cell proliferation and cell migration assays, and a severe DES animal model using rabbits was established with benzalkonium chloride (BAC) treatment for the evaluation.Results: Results showed that the optimal eye formulation contained PRP activated by 350 μg/mL of the low-molecular-weight chitosan group (L3) combined with 300 μg/mL TO50SC (L3+T050SC). In the WST-1 cell-proliferation assay, L3 and L3+TO50SC significantly increased Statens SIRC cell proliferation after 24 hrs of incubation. In the SIRC cell migration assay, the L3+TO50SC group showed a wound-healing efficiency of 89% after 24-hr treatment. After 5 days of treatment, Schirmer’s test results did not simulate the dry eye animal model. Typical cornea appearance and eye fluorescein staining results showed that the L3 group had the best effect on improving cornea haze and epithelial damage.Conclusion: This study has determined that TOSCNFs effectively promoted the healing effect on severe cases of corneal damage, and also might enhance the clinical application and medical potential of PRP in ophthalmology.Keywords: TEMPO-oxidation, sacchachitin, PRP, dry eye syndrome, nanofibersLin HLWu THHo HOChao FCWu MHLiu DZChen LCSheu MTDove Medical Pressarticletempo-oxidationsacchachitinprpdry eye syndromenanofibersMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 1721-1730 (2020)
