Overexpression of Heme Oxygenase-1 in Mesenchymal Stem Cells Augments Their Protection on Retinal Cells In Vitro and Attenuates Retinal Ischemia/Reperfusion Injury In Vivo against Oxidative Stress

Figure 5

Effects of MSC-HO-1 on retinal cell apoptosis after I/R injury. At day 21, the retinas of control, I/R + PBS, I/R + MSC, or I/R + MSC-HO-1 group were stained utilizing TUNEL and DAPI. TUNEL staining is denoted in red and DAPI staining of nuclei in blue.
