Fluid shear triggers microvilli formation via mechanosensitive ...
2015年11月13日 · Here we demonstrate that fluid shear stress (FSS), an external mechanical cue, serves as a trigger for microvilli formation in human placental trophoblastic cells. We …
The Many Roles of Myosins in Filopodia, Microvilli and Stereocilia
An important group of plasma membrane protrusions, filopodia, microvilli and stereocilia, are supported by parallel bundles of actin. These specialized projections have critical roles in …
Microvilli (SEM, deep etching) | Epithelium - Histology Guide
Scanning electron microscopy (SEM) of microvilli on intestinal epithelial cells. This specimen was prepared using a technique known as deep etching. Etching removes ice from the surface of …
Actin dynamics drive microvillar motility and clustering during …
2019年9月9日 · Strikingly, we found individual microvilli exhibit persistent active motility, translocating across the cell surface at ~0.2 μm/min. Perturbation with inhibitors and …
Rhombic organization of microvilli domains found in a cell model …
Generally, the hexagonal arrangement of microvilli is assumed to be confined to areas with a maximal density (>35 MV/μm) of microvilli. Here, AFM revealed microvillar lattice structures …
3D diversiform dynamic process of microvilli in living cells
2022年12月20日 · Here we used atomic force microscopy (AFM) to achieve nanoscale resolution 3D microvilli images of living HeLa cells. We found that there were mainly two subtypes of …
Microvilli regulate the release modes of alpha-tectorin to …
2024年1月4日 · Alpha-tectorin/TECTA is a glycosylphosphatidylinositol (GPI)-anchored ECM protein essential for TM organization. Here, we identified that TECTA is released by distinct …
Morphological changes in isolated lymphocytes during …
A quantitative comparison of isolated lymphocytes prepared for SEM by the critical-point drying (CPD) and freeze drying (FD) methods revealed that the mean cellular diameter dropped from …
Trogocytic molting of T cell microvilli upregulates T cell receptor ...
2023年5月24日 · We show that T cell activation results in the shedding of TCRs in T cell microvilli, which involves a combined process of trogocytosis and enzymatic vesiculation, leading to the …
Adhesion-based capture stabilizes nascent microvilli at epithelial …
2023年10月23日 · To begin to understand how microvilli are stabilized and accumulate in large numbers during differentiation, we first examined the distribution of nascent protrusions early …
