Cell-in-Cell Events in Oral Squamous Cell Carcinoma

Frontiers in Oncology, 2022
For over a century, cells within other cells have been detected by pathologists as common histopathological findings in tumors, being generally identified as “cell-in-cell” structures.

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.

Cell Migration with Multiple Pseudopodia: Temporal and Spatial Sensing Models [PDF]

, 2013
Cell migration triggered by pseudopodia (or “false feet”) is the most used method of locomotion. A 3D finite element model of a cell migrating over a 2D substrate is proposed, with a particular focus on the mechanical aspects of the biological phenomenon.

Generation and regulation of microtubule network asymmetry to drive cell polarity [PDF]

, 2020
Microtubules control cell architecture by serving as a scaffold for intracellular transport, signaling, and organelle positioning. Microtubules are intrinsically polarized, and their orientation, density, and post-translational modifications both respond

Investigation of Energy Absorbing and Damage Behavior of Gyroid and Diamond Cell Based Lattice Structures Manufactured through Powder Bed Fusion Technology

International Journal of Automotive Science and Technology, 2023
Cellular porous structures are used as an alternative to blocking structures in in-dustrial fields where multi-functionality and mechanical efficiency are necessary.

Cell Competition and its role in the regulation of cell fitness from development to cancer [PDF]

, 2016
Cell competition is a cell fitness-sensing mechanism conserved from insects to mammals that eliminates those cells that, although viable, are less fit than their neighbors. An important implication of cell competition is that cellular fitness is not only

Prevalence of heterotypic tumor/immune cell-in-cell structure in vitro and in vivo leading to formation of aneuploidy. [PDF]

PLoS ONE, 2013
Cell-in-cell structures refer to a unique phenomenon that one living cell enters into another living cell intactly, occurring between homotypic tumor cells or tumor (or other tissue cells) and immune cells (named as heterotypic cell-in-cell structure ...

Induction of Live Cell Phagocytosis by a Specific Combination of Inflammatory Stimuli

EBioMedicine, 2017
Conditions of severe hyper-inflammation can lead to uncontrolled activation of macrophages, and the ensuing phagocytosis of live cells. However, relationships between inflammatory stimuli and uncontrolled phagocytosis of live cells by macrophages are ...

Cell-in-cell phenomenon associates with aggressive characteristics and cancer-related mortality in early oral tongue cancer

BMC Cancer, 2020
Background Cell-in-cell structures (caused by cell cannibalistic activity) have been related to prognosis of many cancers. This is the first multi-institutional study to assess the prognostic impact of cell-in-cell structures in a large cohort of early ...

Chemotaxis: a feedback-based computational model robustly predicts multiple aspects of real cell behaviour [PDF]

, 2011
The mechanism of eukaryotic chemotaxis remains unclear despite intensive study. The most frequently described mechanism acts through attractants causing actin polymerization, in turn leading to pseudopod formation and cell movement.
