Figure 5. rAV-GFP transduction of organ-cultured normal corneas. Upper left, live cornea; other panels, transverse corneal sections (combined fluorescence and transmitted light). Mostly epithelial (A,B) and some endothelial cells (D) are transgene-positive, whereas stromal keratocytes (C) are negative. e, epithelium; s, stroma; DM, Descemet’s membrane. Direct fluorescence. Bar=20 μm.
