Fig. 7From: Identification of the principal neuropeptide MIP and its action pathway in larval settlement of the echiuran worm Urechis unicinctusLocation of Tctex1d2 and Cfap45 mRNA in U. unicinctus embryos and larvae detected by Whole-mount in situ hybridization. A: Tctex1d2; B: Cfap45; a and a’: zygote; b and b’: 4-cell embryo; c and c’: 8-cell embryo; d and d’: multicellular embryo; e and e’: blastula; f and f’: gastrula; g and g’: early-trochophore; h and h’: mid-trochophore; i and i’: late-trochophore; j and j’: early-segmentation larva; k and k’: late-segmentation larva; l and l’: worm-shaped larva. Blue indicates the positive signal. AT: apical ciliary tuft; CR: circumoral ciliary ring; TT: telotroch. All scales are 50 μmBack to article page
