Figure 5. RPE cells were identified that appear to be going through full cell division. In the peripheral retinal regions, a small number of cells could be identified that appeared to be passing through full cell division. In both pictures, arrows point to two labeled nuclei that appear to be forming a plasma membrane between them. Both sets of cells appear irregular in the RPE cell matrix. Taken together with the finding that there was no increase in the number of binucleated cells in the peripheral retina, these photographs demonstrate that at least some of the cells in this region were undergoing full cell division.
