Figure 4. Various tissues showing convergent extension. Classification of CE models based on the crawling and contraction modes. Membrane protrusions are observed during CE in the mouse neural plate, Xenopus laevis notochord, and Ciona intestinalis notochord (i.e., crawling mode: blue circle). The formation of X. laevis notochord also exhibits the contraction mode, and it is thought that the mouse neural plate and C. intestinalis notochord also display the contraction mode. Cell–cell junction contractions are observed during CE in Drosophila melanogaster germband extension, chick neural tube elongation, and X. laevis kidney tubule elongation (i.e., contraction mode: red circle). Although there are other developmental processes showing CE, their modes are unclear (green box). Image published in: Shindo A (2018) © 2017 The Authors.
