The methods of this research were isolated mesenchymal stem cells from the bone marrow of adult wild-type Sprague-Dawley (SD) rats. BM-MSCs were cultured under normoxic or hypoxic (1% oxygen for 24 hours) conditions. Normoxic or hypoxic BM-MSCs were transplanted intravitreally 1 week after ocular hypertension induction by acutely increasing IOP to 100 - 120 mmHg for 60 minutes. Rats were killed 4 weeks after transplanted. Apoptosis was examined by tunnel assay and expression Brn3b (Brn3b = RGCs marker) by immunohistochemical analysis of the retina. Results showed that transplantation of hypoxic preconditioning BM-MSCs in acute glaucoma models resulted in a significant apoptosis decreasing (p < 0.05) and an significant increasing in RGCs (p < 0.05), as well as enhanced mor-phologic and functional benefits of stem cell therapy versus normoxic BM-MSCs transplantation. Conclusions: Hypoxic preconditioning enhances the capacity of BM-MSCs transplantation to improve neuroprotective effects of RGCs in Acute Glaucoma Models.展开更多
