Fig. 1. Mesoderm formation in the larva of the brachiopod Coptothyris grayi: (a) – late bilaterally symmetrical gastrula (15 bpo), SEM, (b) – formation of the anterior mesoderm at the stage of late gastrula, partial Z-projection of the part after DAPI staining, CLSM, (c) – formation of the posterior mesoderm at the stage of late gastrula gastrules, partial Z-projection after DAPI staining, KLSM, (d) – early three–lobed larva (22 hpo), SAM, (e) - Z–projection of early three-lobed larva after DAPI staining, KLSM, (e) - Z-projection of early three-lobed larva after phalloidin staining, KLSM. (al) – head blade, (am) – anterior mesoderm, (ar) – archenteron, (bl) – blastopore, (pl) – foot blade, (pm) – posterior mesoderm, (rml) – rudiment of the mantle blade, arrows point to the anterior mesoderm, arrow tips point to the posterior mesoderm. |
