FIG. 5. Trunk somites I-VIII contribute to the ventral body wall. Embryos were stained for pax3 followed by 12/101 antibody staining. A
stage-31 embryo (A) shows that the three remaining head somites (arrow heads) do not contribute pax3-positive cells to the ventral body
wall. A stage-36 embryo (B) shows that trunk somites VII and VIII (arrows) are the last somites to contribute to the ventral body wall.
FIG. 6. DiI labeling of migrating myoblasts (A). Arrows mark three points of injection along the anteriorosterior axis targeting the
ventro-lateral region of the somites (A). As development of this embryo proceeds, cells labeled by the anterior-most injection migrate first
and farthest (B, C, arrows). The cells labeled by the posterior-most injection in the tail region show very little migration. |
