prepattern
The results confirm previously recorded results of the spherical region upon which a prepattern theory of mitosis and cytokinesis is based.
      
The results confirm previously recorded results of the spherical and prolate regions, upon which a prepattern theory of mitosis and cytokinesis is based.
      
Especially, the phenomenon of 90 degree axis tilting and the formation of a highly symmetrical saddle shaped pattern, crucial for the prepattern theory of mitosis and cytokinesis, is examined.
      
The bipolar "mitosis" prepattern is found as well, although the polar axis may appear with an angle toward the axis of the oblate spheroid.
      
These results are thus further support for the prepattern theory of mitosis and cytokinesis.
      
These results strongly support the prepattern model for mitosis and cytokinesis and the viewpoint that prepatterns play a fundamental role in nature.
      
As real biochemical systems like cleaving eggs or early embryos vary considerably in size, Turing prepatterns are unable to maintain a specified prepattern-geometry, unless D/R2 is varied as well.
      
This prepattern becomes manifest when parts of larvae are brought to metamorphosis immediately after isolation.
      
Between stages 35-36 and 38 they were arranged in a prepattern of several distinct, mixed chromatophore groups along the dorsal trunk, morphologically correlated in the scanning electron microscope with humps on the original crest cell string.
      
Inhibitor I appears to be a factor of this prepattern.
      
Signal transmission and covert prepattern in the metamorphosis of Hydractinia echinata (Hydrozoa)
      
The overt pattern of the polyp is, therefore, generated under the influence of a covert anterior-posterior prepattern of the larva.
      
This was interpreted in terms of a prepattern in the ectoderm.
      
Pattern formation during insect leg segmentation: Studies with a prepattern of a cell surface antigen
      
The temporal and spatial distribution of the antigen indicates the existence of a prepattern for leg segmentation, examination of which can give information about pattern generating mechanisms.
      
A corresponding prepattern was established in bisected animals at least 10 h before the regenerating structure began to form.
      
The combined data from the three brain regions suggest that glial cells can prepattern the neuropilar boundaries.
      
Quantitative developmental genetic analysis reveals that the ancestral dipteran wing vein prepattern is conserved in Drosophila
      
Engrailed represses Delta, which is ubiquitously expressed throughout the prospective hindgut region in early blastodermal stages, in the dorsal domain, and thus generates a Delta-positive/negative prepattern.
      
A set of extracellular signals establishes the positional information in the ectoderm, which activates Prepattern genes (Gli, Xiro, Zic, Dlx, etc.) across extended and overlapping domains.
