Editing Invagination (section)

=== Supracellular cables ===
Supracellular actomyosin cables are structures of actin and myosin that align between cells next to each other and are connected by cell junctions.<ref name=":4" /> These cables play many roles in morphogenesis during embryonic development, including invagination.<ref name=":5">Röper, Katja. 2013. “Supracellular Actomyosin Assemblies during Development.” BioArchitecture 3 (2): 45–49. <nowiki>https://doi.org/10.4161/bioa.25339</nowiki>.</ref> Rather than solely relying on apical constriction of individual cells, invagination can be driven by compressive forces from this cable contracting around the site of invagination, such as in the case of [[salivary gland]] invagination in ''Drosophila''.<ref>Röper, Katja. 2012. “Anisotropy of Crumbs and aPKC Drives Myosin Cable Assembly during Tube Formation.” ''Developmental Cell'' 23 (5): 939–53. <nowiki>https://doi.org/10.1016/j.devcel.2012.09.013</nowiki>.</ref><ref>Chung, SeYeon, Sangjoon Kim, and Deborah J Andrew. 2017. “Uncoupling Apical Constriction from Tissue Invagination.” Edited by Hugo J Bellen.
