Three-dimensional rendering of mesoderm cells in early, flat neural plate stage Xenopus (stage 14) and post neural tube closure (stage 21). Scattered cells within a whole embryo labeled with Lifeact-eGFP. Scale bar 20μm. Multiscale analysis of architecture, cell size and the cell cortex reveals cortical F-actin density and composition are major contributors to mechanical properties during convergent extension Joseph H.
