Figure 1. Gene expression in freshly harvested or proliferation-cultured E13.5 retinal progenitor cells (RPCs) relative to fresh E17.5 RPCs. Expression of each gene in freshly harvested E17.5 RPCs was defined as 1. The columns represent the relative expression level in E13.5 RPCs, which were either freshly harvested (black column) or proliferation-cultured for 4 days (red column). Panel A shows the genes whose initial expression was high in fresh E13.5 RPCs, but mostly decreased after 4 days culture. Panel B represents those genes whose initial expression was low in fresh E13.5 RPCs, but increased after 4 days culture. Note that the expression change of Math5, Brn3b, and Islet1 in E13.5 RPCs was exceptional. The symbols * and ** represent p<0.05 and p<0.01, respectively, versus fresh E17.5 RPCs. The symbols # and ## represent p<0.05 or p<0.01, respectively, versus fresh E13.5 RPCs. Data was mean±standard deviation (n=4). The significance was estimated by one-way ANOVA.
