Reaction-diffusion pattern in shoot apical meristem of plants. [PDF]

open access: yesPLoS ONE, 2011
A fundamental question in developmental biology is how spatial patterns are self-organized from homogeneous structures. In 1952, Turing proposed the reaction-diffusion model in order to explain this issue.

Specific Eph receptor-cytoplasmic effector signaling mediated by SAM–SAM domain interactions

open access: yeseLife, 2018
The Eph receptor tyrosine kinase (RTK) family is the largest subfamily of RTKs playing critical roles in many developmental processes such as tissue patterning, neurogenesis and neuronal circuit formation, angiogenesis, etc.

Involvement of the conserved Hox gene Antennapedia in the development and evolution of a novel trait

open access: yesEvoDevo, 2011
Background Hox proteins specify segment identity during embryogenesis and have typical associated expression patterns. Changes in embryonic expression and activity of Hox genes were crucial in the evolution of animal body plans, but their role in the ...

Spatial patterning of the epigenome during vertebrate gastrulation

open access: yesNature Communications
A central question in developmental biology is how embryonic cells acquire and store positional information during pattern formation. In vertebrates, this process begins with the localized activation of signaling systems that mediate axial specification.

Primordial Germ Cell Specification and Migration [version 1; referees: 3 approved]

open access: yesF1000Research, 2015
Primordial germ cells are the progenitor cells that give rise to the gametes. In some animals, the germline is induced by zygotic transcription factors, whereas in others, primordial germ cell specification occurs via inheritance of maternally provided ...

A Cellular Potts Model of the interplay of synchronization and aggregation [PDF]

open access: yesPeerJ
We investigate the behavior of systems of cells with intracellular molecular oscillators (“clocks”) where cell-cell adhesion is mediated by differences in clock phase between neighbors.

Numerical framework and stability analysis of the Gray-Scott model

open access: yesOpen Computer Science
Turing models of pattern formation provide insight into an intriguing question in developmental biology, like how nature exhibits various structures, shapes, and organized patterns. These natural patterns include the pattern and texture on a desert dune,

Towards a bioinformatics of patterning: a computational approach to understanding regulative morphogenesis

open access: yesBiology Open, 2012
Summary The mechanisms underlying the regenerative abilities of certain model species are of central importance to the basic understanding of pattern formation.

Automatic design of gene regulatory mechanisms for spatial pattern formation

open access: yesnpj Systems Biology and Applications
Gene regulatory mechanisms (GRMs) control the formation of spatial and temporal expression patterns that can serve as regulatory signals for the development of complex shapes.
