Abstract

Decellularized corneas obtained from other species have gained intense popularity in the field of tissue engineering due to its role to serve as an alternative to the limited availability of high-quality donor tissues. However, the decellularized cornea is found to evoke an immune response inspite of the removal of the cellular contents and antigens due to the distortion of the collagen fibrils that exposes certain antigenic sites, which often lead to graft rejection. Therefore, in this study we tested the hypothesis that cross-linking the decellularized corneas with chondroitin sulfate may help in restoring the distorted conformationation changes of fibrous matrix and thus help in reducing the occurrence of graft rejection. Cross-linking of the decellularized cornea with oxidized chondroitin sulfate was validated by ATR-FTIR analysis. An in vitro immune response study involving healthy monocytes and differentiated macrophages with their surface marker analysis by pHrodo red, Lysotracker red, ER tracker, and CD63, LAMP-2 antibodies confirmed that the cross-linked decellularized matrices elicited the least immune response compared to the decellularized ones. We implanted three sets of corneal scaffolds obtained from goat, i.e., native, decellularized, and decellularized corneas conjugated with chondroitin sulfate into the rabbit stroma. Histology analysis, three months after implantation into the rabbit corneal stromal region, confirmed the restoration of the collagen fibril conformation and the migration of cells to the implanted constructs, affirming proper graft integration. Hence we conclude that the chondroitin sulfate cross-linked decellularized corneal matrix may serve as an efficient alternative to the allograft and human cadaveric corneas.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
