Group survival time The Kaplan–Meier survival plot of corneal allografts in mesenchymal stem cell (MSCs)-treated and untreated rat (a). When compared with vehicle-treated rats (Group A) (9.8 ± 1.2 days), rats receiving postoperative, dual injections of MSCs (Group D) (12.6 ± 1.4 days, p = 0.002) had significantly prolonged graft survival time. A single MSCs injection (Group C) (10.8 ± 1.3) did not result in statistically significant changes in graft survival time. However, preoperative MSCs (Group B) (8.0 ± 0.9 days, p = 0.007) accelerated graft rejection time when compared with controls. The scores of neovascularization (b) and opacity (c) are shown over time
