Corneal Decellularization: A Method of Recycling Unsuitable Donor Tissue for Clinical Translation?

Abstract

The ability to utilize, reprocess and regenerate tissues deemed "unsuitable" for transplantation allows us to salvage valuable tissue. Reprocessing the tissue has the potential to have a considerable impact on addressing the problems associated with cadaveric donor shortage. Patients would directly benefit by accessing greater numbers of corneal grafts and health authorities would fulfill their responsibility for the delivery of effective corneal reconstruction to alleviate corneal blindness. However, in order to progress, we may need to take a step back to establish a "decellularization" criterion; which should balance effective removal of immune reactive material with maintenance of tissue functionality.
