Endogenous OptoRhoGEFs reveal biophysical principles of epithelial tissue furrowing

Andrew D. Countryman, Caroline A. Doherty, R. Marisol Herrera-Perez, Karen E. Kasza

The paper uses optogenetic tools to control RhoGEF activity in Drosophila and reveals how RhoGEF recruitment affects tissue furrowing during development.

E-cadherin tunes tissue mechanical behavior before and during morphogenetic tissue flows

Xun Wang, Christian Cupo, Sassan Ostvar, Andrew D. Countryman, Karen E. Kasza

This study investigates how E-cadherin-mediated adhesion affects mechanical behavior in Drosophila epithelial tissues before and during morphogenetic flows, revealing dual roles in tissue structure and dynamics.
