Retina and RPE flat mounts from Mertk ^−/− Cx3cr1 ^GFP/+ Ccr2 ^RFP/+ mice of different ages. a Retina flat mounts from 5-, 6-, and 18-week-old Mertk ^−/− Cx3cr1 ^GFP/+ Ccr2 ^RFP/+ mice are shown. The number of Cx3cr1-GFP and Ccr2-RFP-positive cells in retina flat mounts of 5-, 6-, and 18-week-old Mertk ^−/− Cx3cr1 ^GFP/+ Ccr2 ^RFP/+ mice was counted. b RPE flat mounts of 5-, 6-, and 18-week-old Mertk ^−/− Cx3cr1 ^GFP/+ Ccr2 ^RFP/+ mice are shown. The number of Cx3cr1-GFP and Ccr2-RFP-positive cells in RPE flat mounts of 5-, 6-, and 18-week-old Mertk ^−/− Cx3cr1 ^GFP/+ Ccr2 ^RFP/+ mice was counted. Asterisk indicates P < 0.05 vs 4-week-old Mertk ^−/− Cx3cr1 ^GFP/+ Ccr2 ^RFP/+ mice
