We investigated if bone marrow stromal cells (BMSCs) transplanted into the vitreous body of a glaucoma model eye could be integrated in the host retina and also whether they could rescue the retinal ganglion cells (RGCs) from death induced by the elevated intraocular pressure. Glaucoma was induced in the right eye of adult Wistar rats by ligating the episcleral veins. The GFP-expressing BMSCs (GFP-BMSCs) were injected into the vitreous body of both the control and the glaucomatous eyes. After transplantation, GFP-BMSCs were mostly present along with the inner limiting membrane and only a few cells were integrated into the ganglion cell layer. At 2 or 4 weeks after transplantation, GFP-BMSCs were observed to express various trophic factors. The BMSCs injected glaucoma model eyes showed less reduction in the number of RGCs compared to the glaucomatous eyes with PBS injection. This study suggests that BMSC transplantation may be worthy as a neuroprotective tool to treat glaucoma.
