Fig. 4 (Left). Relaxation-promoted formation of additional groups of bottle-shaped cells and the corresponding invaginations (shown in A,
D by dense pointers) (A) 1 h after the relaxation of the suprablastoporal zone due to its separation from the underlain tissues (large bent arrow) at
the early gastrula stage. blp is the normal blastopore. (B) A saggital section of the dorsal blastoporal lip of the normal mid-gastrula stage embryo.
Arrows show separation directions which relax pre-existed tensions. (C) A relaxed lip immediately after separation (D) 1 h later, a new invagination
pit has been formed at the site of a former dorsal blastoporal lip (pointer). 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 |
