Figure 8. Rods and cones distribution in 3-week-old rd10 mice injected with buffer saline sodium or human transferrin. Cones (A-C) and rods (D-F) were localized on frozen sections from mice daily intraperitoneally injected with BSS (A, D) or 24 mg/ml (B, E), and 48 mg/ml (C, F) of hTf since day 5 and sacrificed at 25 days postnatally. Cones were labeled with peanut-agglutinin coupled with fluorescein isothiocyanate (FITC), and rods with antibodies against rhodopsin (Rho4D2). Abbreviations: IS is inner segment of the photoreceptors; ONL is outer nuclear layer. Scale bars in A-C equal 10 μm; in D-F they equal 50 μm.
