The paper investigates how mesoderm invagination affects ectoderm extension during Drosophila gastrulation and finds that cellular mechanisms of axis extension are robust to this mechanical pull.

The paper shows that tissue-scale force balance, not cell-autonomous shape changes, drives epithelial buckling and initiates gastrulation in Drosophila embryos.

The paper identifies different temporal roles for Tartan and Toll-2 LRR receptors in actomyosin enrichment and polarization at parasegmental boundaries in Drosophila embryos.

This study identifies Sidekick as a tricellular adherens junction protein in Drosophila, showing its role in polarized cell intercalation and epithelial integrity during axis extension.

The paper shows that localized actomyosin tension at compartment boundaries orients cell division in Drosophila embryos, independent of cell geometry.

The paper models how geometric features of the Drosophila embryo guide tissue-scale deformations through actomyosin contractility.
