B cell zone reticular cell microenvironments shape CXCL13 gradient formation

Nature Communications, 2020
Morphogens such as chemokines form gradients to direct graded responses and modulate cell behaviors. Here the authors show, using imaging and computer simulation, that the chemokine CXCL13 originated from follicular reticular cells in the lymph nodes ...

Subcellular positioning during cell division and cell plate formation in maize

Frontiers in Plant Science, 2023
IntroductionDuring proliferative plant cell division, the new cell wall, called the cell plate, is first built in the middle of the cell and then expands outward to complete cytokinesis.

Intracellular trafficking of pigeon β-very low density lipoprotein and low density lipoprotein at low and high concentrations in pigeon macrophages

Journal of Lipid Research, 2000
Foam cell formation occurs in vitro at lipoprotein concentrations above 50 μg/ml in pigeon macrophages. Hypothetically, intracellular trafficking of lipoproteins at higher concentrations may differ from uptake of lipoproteins associated with low ...

PCDH7 Inhibits the Formation of Homotypic Cell-in-Cell Structure

Frontiers in Cell and Developmental Biology, 2020
Though homotypic cell-in-cell (hoCIC) structures are implicated in the development and progression of multiple human tumors, the molecular mechanisms underlying their formation remain poorly understood.

Endothelial cell division in angiogenic sprouts of differing cellular architecture [PDF]

, 2015
The vasculature of the zebrafish trunk is composed of tubes with different cellular architectures. Unicellular tubes form their lumen through membrane invagination and transcellular cell hollowing, whereas multicellular vessels become lumenized through a
