Fig. 6. Quantitation of virus-transduced retinal cells that became immunoreactive for a series of cell type-specific markers. (A) P0 retinas infected in vivo. (B) E17.5 retinal explants infected in vitro. Each histogram represents the mean±s.d. for three or four retinas. More than 530 GFP⁺ cells were scored in each retina. ChAT, choline acetyltransferase; GAT-1, GABA transporter 1; GLYT1, glycine transporter 1; GS, glutamine synthase; TH, tyrosine hydroxylase.
