Figure 3. Functional breakdown of upregulated, downregulated, differentially regulated, and “neighbors” data sets. The differentially regulated data set represents genes differentially regulated in all comparisons of retinal progenitor cells (RPCs) versus P1, RPCs versus P5, P1 versus P5 but not significantly changed between fluorescence-activated cell sorting (FACS) positive and negative samples. Pie charts were generated in MS Excel from the categories most significantly overrepresented in each gene list (Benjamini corrected p value <0.01) as assessed with DAVID.
