Fig. 1 Transcription of the kal1a and kal1b genes and accumulation of anosmin-1a and anosmin-1b, throughout PLLP migration. In situ detection of kal1a (A–F and J) and kal1b (G–I and K) transcripts in 22 to 38 hpf whole-mount embryos. Magnified views of the primordium at 32 hpf (J and K). The direction of migration is from anterior to posterior. Whole-mount immunodetection of anosmin-1a (L–N) and anosmin-1b (M–O) in 30 hpf embryos. Magnified views of the embryos shown in panels L (N) and M (O). Prim: PLLP; L2: neuromast 2; pL2, pL3: proneuromasts 2 and 3. neu: differentiated neuromasts.
