The results of the current experiments provide useful insights into the mechanics of continental rift architecture, supporting that rift propagation, width and along-axis segmentation may be strongly controlled by the reactivation of pre-existing pervasive crustal fabrics.
Together, our results indicate that Hes7 activity is required along the whole body axis for proper segmentation, but that Hes7 oscillation is not essential during the segmentation of the sacral and adjacent tail area.
By the end of gastrulation (10 hpf), parp3 is expressed at a basal level throughout the embryo with a stronger expression in the axis, while during segmentation (10h 16h), parp3 expression is concentrated in the notochord.
The Wnt genes encode secreted glycoprotein ligands that regulate a wide range of developmental processes, including axis elongation and segmentation.
In Fig. 8, the medial axis and its segmentation of a cowpea root system was computed from a 2D image.
In consideration that the heart of an adult human is approximately 90 mm across in the short axis view, a segmentation was rejected if this distance of the gravity centers was below 30 mm.
The aim of this study was to identify genes/pathways acting in gradients over time and along the anterior-posterior axis during notochord segmentation and immediately prior to mineralisation of the vertebral bodies in Atlantic salmon.
Proper Meis1 expression is essential for body and limb bud axis patterning, brain segmentation, angiogenic patterning, and the proliferation of stem cells in developing organ systems such as retina, heart, and hematopoietic centers.
Moreover, the CMT solutions derived for the events taking place along the MMF fault indicate fault parallel T-axis orientations, suggesting segmentation and development of local extension features.
This late RA signaling activity in the tail-bud is involved in the termination of segmentation and axis elongation (Tenin et al., 2010; Olivera-Martinez et al., 2012).
