Experimental methodology. (A) Experimental groups. To all groups, an ocular trauma (OT) was induced; group 1 received balanced salt solution (BSS), group 2 had an intravitreal implant of 20,000 mouse embryonic stem cells (mESCs) resuspended in 0.025 mL of BSS, and group 3 was treated with an intravitreal implant of 50,000 mESCs resuspended in 0.025 mL of BSS. (B) Experimental methodology. After OT (day 0) and at the first, second, and fourth weeks post-trauma, the groups received their experimental treatment according to the group that they belong to; at 12 weeks post-trauma, rats were sacrificed and the eyes were enucleated for their histopatological and spectroscopy analysis.
