Fig. 1From: Long-term neuronal survival, regeneration, and transient target reconnection after optic nerve crush and mesenchymal stem cell transplantationrMSCs increased RGC survival up to 240 days after crush. a–e Confocal images of flat-mounted retinas. Control retina (contralateral eye) shows numerous Tuj1+ cells and intact axon bundles. a, c Vehicle-injected retinas; b, d rMSC-treated retinas. Arrows point to cell bodies and arrowheads to axon bundles. f, g In rMSC-injected animals, surviving RGCs were significantly increased in both time points after crush. *P < 0.05, **P < 0.01; unpaired t test.
