Coming to Consensus: A Unifying Model Emerges for Convergent Extension.
Huebner RJ, Wallingford JB. Huebner RJ, et al. Among authors: wallingford jb. Dev Cell. 2018 Aug 20;46(4):389-396. doi: 10.1016/j.devcel.2018.08.003. Dev Cell. 2018. PMID: 30130529 Free PMC article. Review.
By contrast, our understanding of another flavor of movement, cell intercalation during convergent extension, is only now emerging. Here, we integrate divergent findings related to intercalation in different settings into a unifying model, paying attention to how th …

PCP and Septins govern the polarized organization of the actin cytoskeleton during convergent extension.
Devitt CC, Weng S, Bejar-Padilla VD, Alvarado J, Wallingford JB. Devitt CC, et al. Among authors: wallingford jb. Curr Biol. 2024 Feb 5;34(3):615-622.e4. doi: 10.1016/j.cub.2023.12.025. Epub 2024 Jan 9. Curr Biol. 2024. PMID: 38199065 Free PMC article.
Convergent extension (CE) requires the coordinated action of the planar cell polarity (PCP) proteins(1)(,)(2) and the actin cytoskeleton,(3)(,)(4)(,)(5)(,)(6) but this relationship remains incompletely understood. ...

Convergent extension: the molecular control of polarized cell movement during embryonic development.
Wallingford JB, Fraser SE, Harland RM. Wallingford JB, et al. Dev Cell. 2002 Jun;2(6):695-706. doi: 10.1016/s1534-5807(02)00197-1. Dev Cell. 2002. PMID: 12062082 Free article. Review.
The lengthening and narrowing of a field of cells, termed convergent extension, contributes to a variety of morphogenetic processes. Focusing on frogs and fish, we review the different cellular mechanisms and the well-conserved signaling pathways that underlie this …

ARVCF catenin controls force production during vertebrate convergent extension.
Huebner RJ, Weng S, Lee C, Sarıkaya S, Papoulas O, Cox RM, Marcotte EM, Wallingford JB. Huebner RJ, et al. Among authors: wallingford jb. Dev Cell. 2022 May 9;57(9):1119-1131.e5. doi: 10.1016/j.devcel.2022.04.001. Epub 2022 Apr 26. Dev Cell. 2022. PMID: 35476939 Free PMC article.
Here, we describe how a poorly characterized adhesion effector, Arvcf catenin, controls Xenopus head-to-tail axis extension. We find that Arvcf is required for axis extension within the intact organism but not within isolated tissues. ...These results provide a comp …

PCP-dependent transcellular regulation of actomyosin oscillation facilitates convergent extension of vertebrate tissue.
Shindo A, Inoue Y, Kinoshita M, Wallingford JB. Shindo A, et al. Among authors: wallingford jb. Dev Biol. 2019 Feb 15;446(2):159-167. doi: 10.1016/j.ydbio.2018.12.017. Epub 2018 Dec 21. Dev Biol. 2019. PMID: 30579764 Free PMC article.
Oscillatory flows of actomyosin play a key role in the migration of single cells in culture and in collective cell movements in Drosophila embryos. In vertebrate embryos undergoing convergent extension (CE), the Planar Cell Polarity (PCP) pathway drives the elongati …

New tools reveal PCP-dependent polarized mechanics in the cortex and cytoplasm of single cells during convergent extension.
Weng S, Devitt CC, Nyaoga BM, Havnen AE, Alvarado J, Wallingford JB. Weng S, et al. Among authors: wallingford jb. bioRxiv [Preprint]. 2023 Nov 8:2023.11.07.566066. doi: 10.1101/2023.11.07.566066. bioRxiv. 2023.

Employing these two techniques, we have revealed a planar cell polarity (PCP)-dependent mechanical gradient both in the cell cortex and the cytoplasm of individual cells engaged in convergent extension. Importantly, the non-invasive nature of these methods holds gre …
