Fig. 8 (Right). Morphological results of suprablastoporal zone (SBZ) transversal stretching, as compared with a similar stretch of neurula
stage embryos. (A) Scheme of SBZ stretching by two needles. (B-F) 24 h results. (B,C) Total views (on frame B, the direction of stretching is
indicated), whereas (D-F) are histological sections made in transversal embryo planes. Note a complete transversal reorientation of the embryo body
including not only the axial rudiments (notochord and somite series), but also the yolk-containing compartments. In (D) and to some extent in (F) part
of the notochord is shifted to the lateral blastoporal lip. (G) A scheme of a similar operation performed at the early neurula stage. (H) Its result, total
view. Contrary to (A-F), the larva fully preserves its initial axis, remaining bound to one of the needles by a thin unstretched tissue thread (later on
disrupted). In (H), pointers indicate the positions of the needles. Image published in: Beloussov LV et al. (2006) Copyright © 2006. Reproduced with permission of the Publisher, University of the Basque Country Press. Larger Image Printer Friendly View |
