Figure 3. ATP-liposomes prevent retinal ischemia-induced necrosis. A: Transmission electron microscopic (TEM) analysis of the ganglion cell layer (GCL) of sham operated (sham) and ischemic retinas treated with ATP (ATP)-, phosphatidylcholine (PC)-liposomes, and PBS 24 h after reperfusion was used to identify necrotic and apoptotic cells. B: Quantitative comparisons in terms of the cell populations showed characteristic features of necrotic (closed column) and apoptotic (open column) cells detected by the analysis of the TEM micrographs. Results represent the mean±standard error of the mean of three to five independent experiments (*p<0.05).
