Fig. 9 Paired-containing and paired-less transcripts from the zebrafish Pax6a BAC transgene are differentially expressed by amacrine cells in the adult mouse retina. (A, B, D) A subset of EGFP-expressing cells in the adult mouse retina coexpress DsRed. Colabeling with syntaxin (C, D) reveals three populations of amacrine cells: syntaxin+/EGFP-/DsRed- (blue cells in panel D), syntaxin+/EGFP+/DsRed- (arrowheads) and syntaxin+/EGFP+/DsRed+ (arrows). DsRed-expressing amacrine cells tend to project neurites to the middle strata of the IPL. Strata divisions were determined based on work by Masland and co-workers ([Masland, 2001] and [Masland, 2004]). Asterisks denote non-specific staining from a secondary antibody needed for these triple-label experiments. Scale bar in panel A applies to all panels.
