Figure 2. Retina pigmentation in lamprey and zebrafish developed from Cas9 and gol gRNA injected embryos.
(a–f) Lateral views of control (a,d) and gol gRNA injected larvae (b,c,e,f) on 19 dpf (days post fertilization). Phenotypes shown include the wild-type (arrow in (d)), mosaic hypopigmentation (arrow in (e)) and no observable pigment (arrow in (f)) in the retina. Zebrafish embryos injected with Cas9 and the appropriate gol gRNA on 2 dpf also showed mosaic pigmentation (h,i) in the retinas. Scale bars: 0.2 mm.
