Abstract

Conjunctival injuries are general but intractable ocular surface diseases, the sequelae of which are particularly challenging to treat. A promising therapy for conjunctival injuries is to employ biodegradable scaffolds to deliver conjunctival epithelial cells for repairing damaged or diseased conjunctiva. In the present study, an ultrathin porous nanofibrous scaffold was fabricated by using collagen and poly(L‑lactic acid‑co‑ε‑caprolactone) (PLCL) and displayed a thickness of 20 µm, with a high porosity and an average fiber diameter of 248.83±26.44 nm. Conjunctival epithelial cells seeded on the scaffolds proliferated well and had a high cell viability. Reverse‑transcription quantitative PCR showed the expression of conjunctival epithelial cell‑specific genes; in addition, there was no significant difference in the inflammatory gene expression between cells grown on collagen/PLCL scaffolds and tricalcium phosphate scaffolds. After co‑culture for 2 weeks in vitro, epithelial cell stratification was observed using hematoxylin and eosin staining, exhibiting three to four epithelial‑cell layers. In conclusion, these results suggested that collagen/PLCL scaffolds have potential application for repairing conjunctival epithelial coloboma.
