Figure 6. TUNEL staining of retinal EC. Retinal ECs were transfected with the pCMV plasmid containing human caspase-14 cDNA and the empty pCMV vector as a control (A). The number of apoptotic cells (green) was significantly increased in caspase-14 expressing pericytes compared to the control (B, C). DAPI (blue) is a nuclear staining (*p<0.05).
