Fig. 6From: A computational study of VEGF production by patterned retinal epithelial cell colonies as a model for neovascular macular degenerationPrediction of VEGF produced by an inverted pattern of cell-containing and cell-free zones. a The inverse pattern illustrated for one cell-free region of diameter 400 μm. b VEGF expression per cell in inverted cell configurations. In these cases, the numbers refer to the diameters of cell-free circles arranged in the same pattern as in Fig. 1 Back to article page
