Fig. 2From: Human mesenchymal stem cell therapy promotes retinal ganglion cell survival and target reconnection after optic nerve crush in adult ratsLong-term neuroprotective effect of hWJ-MSCs on RGCs. High magnification of confocal images of retinas immunostained for Tuj1 (a–d) 60 and 120 days after crush and injection of vehicle (a and b) or hWJ-MSCs (c and d). Arrows indicate RGCs with soma larger than 150 μm2. e Number of RGCs in the ipsilateral retina normalized by the contralateral eye. f Percentage of surviving RGCs with soma larger than 150 μm2 (black bars) at 60 and 120 days after crush and injection of vehicle or hWJ-MSCs. Mean ± SEM. Unpaired parametric t test, *P < 0.5. Scale bar 25 μmBack to article page
