Serotonin and aanat2 localization in PP2-expressing cells analyzed by confocal imaging. Distribution of serotonin-containing cells compared to that of a PP1-expressing cells and b PP2-expressing cells in the pineal organ of adult zebrafish. RFP and GFP were introduced under the aanat2 promoter into zebrafish where c PP1-expressing cells or d PP2-expressing cells were labeled with GFP or RFP, respectively. The pineal organs of 6-days-post-fertilization larval zebrafish are shown. The scale bars represent 50 μm (a, b), and 25 μm (c, d)
