Ectomesodermal descendants from 2c. (A, B) Z-stacks of merged, confocal images from a dorsal (dors) view through a late stage 6 (A) or a stage 8 (B) larva after labeling micromere 2c. The channels are DiI (red), phalloidin (green) and TO-PRO-3 (blue). (A') Single-channel image of DiI staining shown in (A). (B) Cropped, digitally magnified image of the posterior trunk. (B') Single-channel phalloidin image corresponding to the multichannel image in (B). A large endodermal (en) cell and two smaller interstitial (is) cells are indicated. Anterior is to the left in all images.
