Transcription factors expressed in the foregut. al Expression of Lv-mbx begins at 16 hpf in the elongating archenteron (arrowhead in d, e). Lv-mbx is expressed in the foregut from then through 32 hpf and is also expressed at pluteus stages in the ectoderm near the mouth. mx Lv-islet is expressed in the developing foregut from 16 to 32 hpf. Starting at 18 hpf, Lv-islet expression is not just in the foregut but in the stripe of ectoderm near the foregut (q). a′l′ Lv-dmrt is expressed in the foregut from 22 hpf (g′) through 32 hpf. m′x′ Lv-atbf1 is expressed in the ectoderm from 10 to 22 hpf. At 24 hpf, Lv-atbf1 also turns on in the foregut (arrowhead in t′), where it remains through 32 hpf. Scale bars = 50 μm
