Expression of L. asellus retinoid binding proteins and Las-sox9 in 7dpf larva. Column 1: single labeling of gene X. Column 2–4: double labeling of gene X (cyan) and Las-r-opsin (magenta) in the anterior, posttrochal eye and posterior region. Las-RALBP (A1A4), Las-RLBP1 (B1B4) and Las-sox9 (C1C4) are co-expressed with Las-r-opsin in anterior, eye and posterior PRCs. Scale bars: 100 μm in column 1; 5 μm in columns 24
