Severe reduction in proliferation in the postnatal or^J central retina. The effect of Chx10 loss on central retinal proliferation was assessed by counting the proportion of PH3-positive mitotic cells at three time points. By P3, proliferation in the central or^J retina had decreased dramatically. Error bars represent SD. Asterisks indicate significant difference between WT and or^J (P ≤ 0.03). DP, dorsal peripheral; DM, dorsal medial; DC, dorsal central; VC, ventral central; VM, ventral medial; VP, ventral peripheral.
