Pores: circular surface openings of sudoriferous gland ducts; identified by dark color and circular shape; distinguished from spots based on size.
The leading margins of the disc are nearly straight and converge at the tip of the snout at up to a 130° angle; the anterior disc shape distinguishes this species from the similar Atlantic stingray (D. sabina), which has a longer, more acute snout.
Typically, three different spine shapes are distinguished: Mushroom spines, which have a large head and a thin neck; stubby spines which have a large head but no discernible neck; and thin spines, which are slender, filopodia-like protrusions without a discernible head.
In terms of progenitor Leydig cell formation, we used 3β-HSD as the Leydig cell maker combining with cell localization and spindle-like shapes to distinguish the progenitor Leydig cells (arrow) from fetal Leydig cells (arrowhead).
When building the network, the two types of genes are automatically assigned to nodes in a bipartite graph where different colors and shapes can distinguish between them, and two nodes are linked by an edge if an interaction between the corresponding RNAs has been predicted.
Nonetheless, these factors may combine with the more overt features of openness of shapes, character spacing, varied proportions and other shape-distinguishing features that impact overall legibility.
All bays are semicircular or nearly circular in shape, which distinguishes them from estuaries, which are elongated and funnel-shaped with a river running along the centre line and with beaches mainly near the mouth of the estuary.
Thus, with this tool, the different cells' shapes have been distinguished on the obtained cytograms.
A regularly spaced set of red and blue lobular shapes can be distinguished, which are in good agreement with the stress components around an edge threading dislocation [18].
This method, which was motivated by typical experimental setups easily applied to experimental evolution, is theoretically expected to estimate the mutation rate reasonably well and allows distributions of arising beneficial mutations with different shapes to be distinguished.
