Fig. 2 Expression ofbcl2lduring zebrafish development. Lateral views of embryos analyzed by ISH; anterior is to the left and dorsal to the top. (B) and (F) are dorsal view with anterior to the top. Stage is indicated at bottom left. (A)–(D) 24 hpf embryos showing expression in telencephalon (te), diencephalon (di), hindbrain (hb), lens (le), retina (re), posterior blood island (bi), yolk extension (ye) and notochord (no). (E)–(G) 30 hpf embryos showing expression in hindbrain, telencephalon, diencephalon, lens, retina, yolk extension and thyroid primordium (tp). (H) 48 hpf embryo showing expression in diencephalon, midbrain, hindbrain and thyroid primordium. (I) 72 hpf embryos showing expression in brain and thyroid primordium. (J) Cross section with double labeling of bcl2l mRNA (blue) and TG protein (brown) in a 48 hpf embryo showing expression of bcl2l in thyroid cells.
