Fig. 2. Whole-mount in situ hybridization showing the gene expression profile specific to organs and/or tissues in Ciona intestinalis tailbud embryos. Organs and tissues where the gene is specifically expressed are shown in the bottom left-hand corner, while the clone numbers are indicated in the top right-hand corner. Arrowheads in D indicate epithelial sensory cells. br, brain; endo, endoderm; es, endodermal strand; mes, mesenchyme; mus, muscle; nc, nerve cord; noto, notochord; pap, papilla; TLC, trunk lateral cells; TVC, trunk ventral cells. See text for details. Scale bar: 100 µm.
