This study shows that Wnt11 and core PCP components interact reciprocally to establish cell polarity in Xenopus embryos without relying on Wnt gradients.

The paper shows directional alignment of cell types helps maintain planar cell polarity in tissues with multiple cell types.

The paper develops a theoretical model to explain how mechanical properties and cell cycle dynamics regulate volume distribution in germline cysts, leading to oocyte differentiation.

The paper evaluates mechanical features of cell-cell interactions by relating effective pairwise forces to sub-cellular components using vertex model data.

The paper introduces an ImageJ-based tool for 3D registration between microscopic images, enabling alignment and reconstruction of 3D rotated tissues like mouse embryos and organoids.
