dvdy21449-DVDY21449supplfig1.tif1284K Supplement Figure 1: MCM6 protein is detected in several vertebrate species during development.MCM6 expression was examined in embryonic tissues from chick, zebrafish, andXenopus laevis . In each case, MCM6 was readily detectable and corresponded with staining in proliferating cells.
dvdy21449-DVDY21449supplfig2.tif1849K Supplement Figure 2: Ki67 expression in P0 mouse retina.Based on their location and distribution, bright cells are likely to be cells in G2/M. RPCs in other phases of the cell cycle are likely to express Ki67, but the level of detection is low.
