How do individual cells organize into multicellular tissues? Here, we propose that the morphogenetic behaviour of epithelial cells is guided by two distinct elements: an intrinsic differentiation programme that drives formation of a lumen-enclosing monolayer, and a growth factor-induced, transient de-differentiation that allows this monolayer to be remodelled.

TLDR
The importance of plasma membrane compartmentalization and forces that drive morphogenetic events during cystogenesis are discussed.

Modelling glandular epithelial cancers in three-dimensional cultures
TLDR
The important features of epithelial structures grown in 3D basement membrane cultures, and how such models have been used to investigate the mechanisms associated with tumour initiation and progression are reviewed.
Polarity, cell division, and out-of-equilibrium dynamics control the growth of epithelial structures
Mathematical modeling and analysis of 3D epithelial structures indicate that epithelial growth can take place far from mechanical equilibrium, depending on cell–cell and cell–ECM contact, cell
From cells to organs: building polarized tissue
TLDR
This work discusses how conserved polarity complexes, signalling networks, transcription factors, membrane-trafficking pathways, mechanisms for forming lumens in tubes and other hollow structures, and transitions between different types of polarity, such as between epithelial and mesenchymal cells, are used in similar and iterative manners to build all tissues.
Culturing MDCK cells in three dimensions for analyzing intracellular dynamics.
TLDR
This unit discusses technical aspects for culturing and imaging MDCK 3-D culture for both fixed3-D cultures and live-cell imaging to study epithelial architecture and morphogenesis under close-to-physiological conditions.
Polarity in mammalian epithelial morphogenesis.
TLDR
Some important aspects of mammalian epithelial morphogenesis are discussed, from the establishment of cell polarity to epithelial tissue generation, from three-dimensional organotypic cell culture models.

TLDR
Studies on cells grown in improved two-dimensional and three-dimensional-culture systems that closely mimic the in vivo extracellular-matrix environment should provide a more accurate picture of actin-cytoskeletal function in the living organism.

TLDR
Functional and localization experiments indicate that the slug/snail family of transcription factors functions overall as an epithelial phenotype repressor and could represent a key EMT contributor.
Tissue architecture: the ultimate regulator of epithelial function?
TLDR
The role of cell adhesion in the maintenance of tissue structure is discussed and how tissue structure regulates epithelial function is analyzed.
Angiogenesis in vitro
TLDR
This first demonstration of angiogenesis in vitro shows that all the information necessary to develop an entire capillary network in vitro is expressed by one cell type, suggests a mechanism for lumen formation, and offers a possibility of distinguishing between direct and indirectAngiogenesis factors.
Genetic control of branching morphogenesis.
TLDR
The genetic programs that direct formation of the treelike branching structures of two animal organs have begun to be elucidated and suggests a general scheme for patterning branching morphogenesis.
Rac1 orientates epithelial apical polarity through effects on basolateral laminin assembly
TLDR
It is reported that orientation of apical polarity in developing Madin–Darby canine kidney (MDCK) epithelial cysts requires the small GTPase Rac1 and the basement membrane component laminin and Rac1-mediated laminIn assembly in apical pole orientation.
