The paper shows that tissue mechanics, not gene patterning, determine the scaling of collective cell migration velocity with tissue size during development.

The paper introduces a framework to integrate spatial transcriptomics with live morphometrics to infer gene regulatory networks and validate gene function in Drosophila thorax development.

The paper identifies a mechano-chemical feedback mechanism in Drosophila epithelial cells that maintains junction length and shape stability through differential turnover of apicobasal regulators.

This study shows that glial cell adhesion molecules regulate neural stem cell proliferation by modulating mechanical forces and nuclear integrity in Drosophila.

The paper identifies RhoGAP15B as a spatial inhibitor of RhoA that promotes protrusive activity during collective cell migration in Drosophila border cells.

This study shows that membrane lipid composition and endocytosis regulate Wingless release from secreting cells by modulating its dissociation from Wntless.

The paper investigates how epithelial tissues maintain architecture and cell number despite spindle misorientation, identifying mechanical and systemic signaling mechanisms that prevent cell loss.

This study identifies long Toll receptors as mediators of interface surveillance in Drosophila wing imaginal discs, detecting cell fate aberrations through expression level differences between neighboring cells.

This study shows Toll-2 controls homeotic compartment formation and timing of neck morphogenesis in Drosophila by regulating apoptosis and cell rearrangements through PI3K and Src signaling.

The paper identifies Dystrophin-Dystroglycan as essential for cytokinesis efficiency in Drosophila epithelia by regulating ring contraction and preventing membrane regression.

The paper identifies biallelic variants in ARHGAP19 as a cause of motor-predominant neuropathy with conduction slowing in multiple families.

The paper links apical size and deltaA expression to neural stem cell activation and division modes in zebrafish, showing their independence from Notch signaling.

The paper shows how curvature and tension in Drosophila homeotic compartments drive spatiotemporal folding during development.

The paper introduces MuViScopy, a multi-view confocal microscopy technique for live-imaging multiple organs and whole organisms without embedding, demonstrating its use in Drosophila pupal development.

The paper shows that Wnt ligands are not essential for Planar Cell Polarity (PCP) in Drosophila wings, as PCP remains normal in the absence of Wnt signaling.

The paper shows that tricellular junction proteins facilitate the disentanglement of daughter and neighboring cells during epithelial cytokinesis in Drosophila.
