Abstract
Background: The loss of limbal stem cells owing to either corneal burn or inflammation leads to the repopulation of opaque skin over the raw surface of the cornea. It has been proposed that reconstitution of oral mucosal stem cells over this raw surface will mimic the limbal stem cells and restore vision. The efficacy and safety of applying a sheet of cultivated oral mucosal cells as an autologous graft for corneal replacement were evaluated. Case presentation: The study was conducted during 2014–2015 and involved a total of six patients, of whom three had suffered a chemical burn and three had Stevens-Johnson Syndrome (SJS). Oral mucosal tissue was dissected from each patient, seeded onto irradiated J2 fibroblast feeder cells for 14 days, and analyzed for quality and safety 1 day before being transplanted onto the cornea of the affected eyes. After transplantation, topical antibiotic and anti-inflammatory eye drops were instilled four times daily, and the patients wore contact lenses. Subjects were clinically followed for visual acuities and adverse effects at 2, 4, and 6 weeks, 3 and 6 months, and 1 year post-transplantation. Data were presented descriptively. Visual acuities in patients improved at 2 weeks post-surgery. However, two patients with SJS had corneal ulcer at 2 weeks postoperatively. At the 1-year postoperative examination, the eyes of two patients were in good condition with decreased vascularization and epithelial defect. Conclusions: Cultivated oral mucosal epithelial sheet transplantation in limbal stem cell deficiency had a favorable efficacy. In this study, patients with chemical burn had more clinical benefit than those with SJS. Trial registration ClinicalTrials.gov: NCT02415218.
