Background. Adoptively transferring different sources of myeloid-derived suppressor cells (MDSCs) may assist in mice corneal transplant survival. Methods. Allogeneic full thickness corneal transplantation (donor C57BL/6 to recipient Balb/c mice) was performed. Naive myeloid cells, inflammation-induced MDSCs (iMDSCs), and tumor-induced MDSCs (tMDSCs) were purified from bone marrow of naive, cecal ligation and puncture, or tumor-bearing Balb/c mice, respectively. The inhibitory abilities of myeloid cells toward CD4(+) T cell proliferation were accessed by in vitro carboxyfluorescein diacetate, succinimidyl ester (CFSE) assays. Myeloid cells were adoptively transferred to corneal recipients by retroorbital injection after corneal transplantation. Corneal grafts were examined and photographed for a period of 45 days. The growth of corneal graft neovascularization was quantitatively measured by image editing software. Histopathology was performed to evaluate corneal graft inflammation. Results. The iMDSCs and tMDSCs significantly inhibited T cell proliferation in vitro and significantly prolonged corneal allograft survival in vivo. Strikingly, iMDSC transferring significantly reduced neovascularization that was comparable to transferring of tMDSCs, without additional immunosuppression. However, additional adoptive transfer of MDSCs did not further ameliorate corneal survival in these allogeneic corneal transplantationmice. Conclusions. Inflammation-induced MDSC transfer could reduce corneal neovascularization and prolong corneal allograft survival.
