Fig. 9. Expression of Cs-Notch gene. (A) The partial amino acid sequence of Cs-Notch encoded by the cDNA used. Although the sequence lacks the N-terminal half, it contains four EGF repeats, three DSL domains, the transmembrane domain and six ankyrin repeats. (B-F) Expression of Cs-Notch revealed by whole-mount in situ hybridization. (B) Fertilized egg, (C) eight-cell stage embryo, (D) 32-cell stage embryo, (E) neurula and (F) tailbud embryo. Scale bar: 100 µm.
