(A) Retinal HE staining in Group A. The retinal structure was continuous, and its capillary structure was normal. HE 200×. (B1–2) Retinal HE staining in Group B. The tissue layers of the retina were edematous, and the retina developed telangiectatic vessels (black arrow). Many ganglion cells developed vacuolar degeneration (white arrow) at 4 weeks (B1) and 8 weeks (B2). HE 200×. (C and D) Retinal HE staining in Groups C and D. Treatment with MSCs and NSCs attenuated the retinal vascular dysfunction, and the tissue layers of the retina were gradually arranged regularly (white arrow) at 4 weeks and 8 weeks. HE 200×.
