Making stripes
omites, the precursors of vertebrae, striated muscle, and dermis, are laid down in a timed sequence from anterior to posterior. Now, Alexander Aulehla, Bernhard Herrmann (Max-PlanckInstitut für Immunbiologie, Freiburg, Germany), and colleagues report that a gradient and two dueling molecular clocks, all driven directly or indirectly by Wnt3a, combine to create the striped pattern of somites. Th...
متن کاملNeuronal patterning: Making stripes in the spinal cord
A central issue in developmental biology is how positional information encoded by the graded activity of a morphogen is interpreted to subdivide a uniform territory into distinct domains. In Drosophila, this process has been studied in some detail in the context of the early blastoderm and the developing leg and wing imaginal discs. A common mechanistic theme that has emerged from these studies...
متن کاملHolographic stripes.
We construct inhomogeneous asymptotically anti-de Sitter black hole solutions corresponding to the spontaneous breaking of translational invariance and the formation of striped order in the boundary field theory. We find that the system undergoes a second-order phase transition in both the fixed density and fixed chemical potential ensembles, for sufficiently large values of the axion coupling....
متن کاملTiger stripes.
On occasion a high amplitude band-like signal is noted on Doppler spectral recordings of valvular regurgitation (Fig. 1). However, clinically these “tiger stripes” are most often noted with porcine mitral prosthetic valves (Fig. 2), and may be indicative of an acute flail prosthetic leaflet.1–5 These band-like signals appear to be associated with an intracardiac oscillating structure,6 with the...
متن کاملV1 interpatch projections to v2 thick stripes and pale stripes.
Cytochrome oxidase (CO) reveals two compartments in V1 (patches and interpatches) and three compartments in V2 (thin, pale, and thick stripes). Previously, it was shown that thin stripes receive input predominantly from patches. Here we examined the projections to thick and pale stripes in macaques, revealed by retrograde tracer injections. After thick stripe injection, cells were distributed i...
