First, brain patterning defects are not observed with the secretion-defective mutant En2 5E), although its ability to regulate transcription remains unaffected.
The absence of obvious patterning defects in embryos is consistent with adult-onset vasculopathy due to defective VSMC maturation or function in notch3 mutants.
Interruption of this pathway in mice results in CHD and vascular patterning defects.
Spurious vertical and horizontal lines and other serious "fixed pattern" defects become clearly visible, while the ribosome images disappear altogether due to the averaging.
The simulation results indicate that, as a result of 3D effects leading to phase artifacts, pattern defects cannot be simply treated as ideal absorber defects.
Fotaki, V., Price, D. J. & Mason, J. O. Wnt/β-catenin signaling is disrupted in the extra-toes (Gli3 Xt/Xt)) mutant from early stages of forebrain development, concomitant with anterior neural plate patterning defects.
Moreover, a study of a bright field based EUV actinic pattern inspection tool design using a hybrid (2D + 3D) model is presented, showing that the impact of noise sources and optical design on critical pattern defects detection sensitivity.
Using lineage tracing and cell fate markers, we show that, unexpectedly, patterning defects in bdyoda1 mutants do not arise from faulty physical asymmetry in cell divisions but rather from improper enforcement of alternative cellular fates after division.
Genotypes with proper spacing (< 5% of stomata in clusters) achieved Diffusive gsmax values comparable to Anatomical gsmax across a 10-fold increase in stomatal density, while lines with patterning defects (> 19% clustering) did not.
As a consequence, an increase in endocytic localization of EGF receptor (Egfr) and Notch is observed, and this correlates with a reduction in signaling strength and leads to patterning defects.
