(a) Fluorescence and bright-field images of day 2 organoids produced by aggregation of >1000 cells and <1000 cells stained with anti-Rx2 antibody. (b) Analysis of the area of Rx2 (wild-type organoids stained with anti-Rx2 antibody) and Rx3 (Rx3::H2B-GFP-derived organoids stained with anti-GFP antibody) expression area (% of total organoid area) in day 2 organoids. ****p<0.0001. (c) Number of organoids forming (1–4) individual retinal regions produced by aggregation of >1000 (n = 26 for Rx2, n = 9 for Rx3) and <1000 (n = 57 for Rx2, n = 66 for Rx3) cells from nine independent experiments. (d) Size, measured as largest circumference, of the optic vesicle of 1 dpf embryos and optic vesicle-like structures formed by day 2 organoids (n = 16 embryos, n = 56 aggregates from six independent experiments). ns, non-significant. (e) Bright-field and fluorescent images of day 2 Rx3::H2B-GFP organoids stained with anti-GFP antibody. Optical sections of an organoid (day 2) (n = 9/10) and an embryo (1 dpf) stained with anti-Rx2 and anti-Otx2 antibodies. (f) Maximal projection of day 2 organoids and 1 dpf embryo generated from Rx3::H2B-GFP transgenic or wild-type blastulae and stained with neural tissue-specific anti-Sox2 (n = 12/12) and anti-Otx2 (n = 10/10) antibodies, co-stained with anti-Rx2 and DAPI nuclear stain. hpa, hours post-aggregation; dpf, days post-fertilization.
