“…In this article, we image, process, and analyze whole Madin-Darby Canine Kidney (MDCK) 3D epithelial cell cultures. Despite their simplicity, these cysts have previously been used as a suitable model system to study the establishment of cell polarity and cell junctions (Bryant & Mostov, 2008; Dukes et al, 2011; Martín-Belmonte et al, 2008; Vidal-Quadras et al, 2017; Yonemura, 2014), epithelial morphogenesis and physiology (Alfonso-Pérez et al, 2022; Guo et al, 2008; Herranz & Martín-Belmonte, 2022; Imai et al, 2015; O’Brien et al, 2002; Wells et al, 2013; Yu et al, 2007), tumor progression (Fessenden et al, 2018; Sakurai et al, 2012; Schmeichel & Bissell, 2003; L. Yan et al, 2021), and for exploring the constraints on epithelial tissue morphogenesis (Beck et al, 2022). MDCK cysts have provided a lot of useful information to study more complex systems helping to understand the self-organization in organoids, embryoids and the early stages of mammal development (Beck et al, 2022; Carleton et al, 2022; Metzger et al, 2018).…”
