Fig. 5 (Right). Schemes of the operations for modulating σc and/or σm values (shown by dotted lines) in the marginal zone of early gastrula embryos and expected results. (A) A transversal view of a dorso-medial cut (vertical arrow in A) providing wound opening (diverged arrows) and hence σc relaxation, most of all in the ventral region (wavy part of a contour). Wound gap is covered by a piece of ventral ectoderm. (B) Expected cell convergence along a ventral mid-line due to increase of inequality between a preserved σm (vertical bidirectional arrow) and relaxed σc (convex arrow). View from the ventral side. (C) Enhancement of σc in the dorso-medial zone as a result of transversal stretching by two needles (arrows coming from black spots). (D) Expected result; an extensive transversal cell convergence in the area of the suprablastoporal zone and latero-ventral cell movements due to some σc relaxation in the ventral region.
