Behaviour of iridophores in control (albino) and iridophore-deficient (shady) hosts.
(a?c) Iridophore and melanophores clusters (derived from Tg(ß-act:GFP)) in control (albino) analysed with fluorescence (a,c) and bright-field microscopy (b): at 90?dpf iridophores and melanophores cover several stripes spanning between 1 and 4 metameres. (d?g) Confocal images of (Tg(TDL358:GFP))-labelled iridophore clusters in control (albino): iridophores appear in three adjacent metameres at 26?dpf and multiply within the same metameres. (h?l) (Tg(TDL358:GFP; sox10:mRFP)) cluster in shady covers 10 metameres at 35?dpf. Dashed white lines indicate vertical and horizontal myosepta. Red numbers indicate metameres. Scale bars, a?c: 250??m, d?l: 100??m.
