3D Organisation of Cells in Pseudostratified Epithelia

Frontiers in Physics, 2022
Pseudostratified epithelia have smooth apical and basal surfaces, yet along the apical-basal axis, cells assume highly irregular shapes, which we introduce as punakoids. They interact dynamically with many more cells than visible at the surface. Here, we

PERK-dependent reciprocal crosstalk between ER and non-centrosomal microtubules coordinates ER architecture and cell shape. [PDF]

Cell Rep
The architecture of the endoplasmic reticulum (ER) is a key determinant of its function. Its dynamics are linked to those of the cytoskeleton, but our understanding of how this coordination occurs and what its functional relevance is, limited.

Micropatterning of single endothelial cell shape reveals a tight coupling between nuclear volume in G1 and proliferation

, 2008
Shape-dependent local differentials in cell proliferation are considered to be a major driving mechanism of structuring processes in vivo, such as embryogenesis, wound healing, and angiogenesis.

Regulation of cell migration by dynamic microtubules [PDF]

, 2011
Microtubules define the architecture and internal organization of cells by positioning organelles and activities, as well as by supporting cell shape and mechanics. One of the major functions of microtubules is the control of polarized cell motility.

Conserved cellular patterning in the mesophyll of rice leaves

Plant Direct, 2023
The mesophyll cells of grass leaves, such as rice, are traditionally viewed as displaying a relatively uniform pattern, in contrast to the clear distinctions of palisade and spongy layers in typical eudicot leaves. This quantitative analysis of mesophyll

Mechanisms shaping cell membranes [PDF]

Current Opinion in Cell Biology, 2014
Membranes of intracellular organelles are characterized by large curvatures with radii of the order of 10-30nm. While, generally, membrane curvature can be a consequence of any asymmetry between the membrane monolayers, generation of large curvatures requires the action of mechanisms based on specialized proteins.

Modulation of Peptidoglycan Synthesis by Recycled Cell Wall Tetrapeptides

, 2020
The bacterial cell wall is made of peptidoglycan (PG), a polymer that is essential for the maintenance of cell shape and survival. During growth, bacteria remodel their PG, releasing fragments that are predominantly reinternalized and recycled.

Aggregate Filamentous Growth Responses in Yeast

mSphere, 2019
Many fungal species, including pathogens, undergo a morphogenetic response called filamentous growth, where cells differentiate into a specialized cell type to promote nutrient foraging and surface colonization.

“Influence of plasmids, selection markers and auxotrophic mutations on Haloferax volcanii cell shape plasticity”

Frontiers in Microbiology, 2023
Haloferax volcanii and other Haloarchaea can be pleomorphic, adopting different shapes, which vary with growth stages. Several studies have shown that H.

Coordinated and Distinct Roles of Peptidoglycan Carboxypeptidases DacC and DacA in Cell Growth and Shape Maintenance under Stress Conditions

Microbiology Spectrum, 2023
Peptidoglycan (PG) is an essential bacterial architecture pivotal for shape maintenance and adaptation to osmotic stress. Although PG synthesis and modification are tightly regulated under harsh environmental stresses, few related mechanisms have been ...
