Fig. 10 (Right). Residual deformations (RDs) in stretched or shrunk explants of embryonic tissues after their unloading. Vertical axes: percents
of the positive (fixed elongation) or negative (fixed shrinkage ) RDs. Initial length is taken as zero. Horizontal axes: time, minutes. (A) Protocol graphs of
a stretched explant (1) and two shrunk explants (2,3). Explant 1, stretched to 70% at 5 min time and unloaded 6 min later, gradually returned to its initial
length. Meanwhile, explant 2 which was shrunk to 50% and kept in this state for only 2 min gave - 35% RD; explant 3 shrunk for 5 min and gave -100%
RD. (B) RD after unloading 10-20% stretch in 5, 30 and 60 min after its application. (B1) Explants of the early gastrula ventral ectoderm, (B2) SBZ tissue,
(B3) explants of the lateral ectoderm from neurula stage embryos. While in 5 min after force application the samples B1 and B2 undergo 20-10%
contraction, (that is, negative RD), after 60 min stretch, B1 samples gave +20% RD, B2 samples just a slight RD and B3 samples no RD at all. Image published in: Beloussov LV et al.
