Fig. 7. Comparison of mRNA expression patterns. (A-L) Comparison of the mRNA expression patterns of tbx1, follistatin and ptc in zebrafish and lamprey (P. marinus) otic vesicles. (A,C) 28 hpf zebrafish; (E) 30 hpf zebrafish; (I) 20 hpf zebrafish; all others are P. marinus at the stages shown. (C,D,H-J) Dorsal views, anterior to left, medial to top; all others are lateral views, anterior to left, dorsal to top. The otic vesicle is outlined in J for clarity. Scale bars: in A, 50 µm for A,C,E; in B, 50 µm for B,D,F-H,K,L; in I,J, 50 µm.
