Figure 1


Fig. 1. Diagrams showing the fates of cells in the vegetal hemisphere of ascidian embryos. Endoderm-lineage cells are colored yellow. Those for notochord, nerve cord, the brain, mesenchyme and muscle are shown in pink, purple, blue, green and red, respectively. (A,B) Lateral views; anterior is to the left. (A) Tailbud embryos. Upper and lower diagrams illustrate midsagittal and parasagittal sections, respectively. (B) An eight-cell-stage embryo. Fate map of major larval tissues and the name of each blastomere are indicated. (C,D) Vegetal views. Anterior is up. The cells shown by ellipses at the top of each diagram are blastomeres in the animal hemisphere, which are behind the vegetal hemisphere. (C) A 32-cell-stage embryo. Cells expressing FGF9/16/20 are highlighted by black dots. Light blue arrows indicate direction of FGF signaling. Red hatching indicates the proposed area where macho-1 functions. (D) A 64-cell-stage embryo. The pairs of blastomeres connected with bars are sister blastomeres. Br, brain; En, endoderm; Epi, epidermis; Mes, mesenchyme; Mus, muscle; NC, nerve cord; Not, notochord.
