Fig. 6 The expression pattern of tnni-HC transcript during the development of zebrafish embryos. Embryos at different stages as indicated were collected and hybridized with tnni-HC using whole-mount in situ hybridization. Panels A, B, C, D and F were dorsal view, anterior of embryo to the top; and panels E and G were lateral views, anterior of embryo to the left. tnni-HC was expressed in the heart exclusively during early cardiogenesis at 16–48 hpf, but it was not only in the craniofacial muscle but also in the heart after 48 hpf. so, superior oblique; io, inferior oblique; sr, superior rectus; ir, inferior rectus; lr, lateral rectus; mr, medial rectus; sh, sternohyoideus; lap, levator arcus palatini; ao, adductor hyoideus; imp, intermandibularis posterior; ima, intermandibularis anterior; ih, interhyoideus; hh, hyohyoideus; hm, hapaxial muscles; V, ventricle; A, atrium.
