MorphoGraphX is a user-friendly image processing software primarily aimed at segmenting 3D biological images into cells, quantifying cellular gene expression and growth, and understanding these data in the spatial context of developing organs.

In stau^-mutants, the Hunchback boundary shifts posteriorly by 10% EL but shows comparable variability to that of the wild type in short time windows in nuclear cycle 14.

Maternal positional information in the fly embryo can be read rapidly in spite of the gene-expression bottleneck and general examples of regulatory architectures that combine speed and accuracy are provided.

A shift in antero-posterior positional information may contribute to the fin-to-limb transformation.

Homeostatic tissue maintenance can occur at locations distinct from the target sites of organ regeneration planarians.

The hunchback transcription features are compatible with an equilibrium model with a short decay length Bicoid activity gradient as the sole source of positional information, while Zelda and Hunchback speed-up the process by different means.

Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

NR4A is a broadly conserved transcription factor that is required for concordance of patterning information and anatomy at both ends of the planarian anterior-posterior axis.

Progenitors establish a single-cell length WNT morphogen gradient to transmit signals directionally and differentially to neighbors.

Intracellular protein gradients, which are formed by the combined action of cytoplasmic diffusion and cortical transport toward the cell pole, are solely determined by cell shape.
