Cell-in-Cell Events in Oral Squamous Cell Carcinoma [PDF]

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. Despite their characteristic morphology, these structures can originate from various processes, such as cannibalism, entosis and emperipolesis. However, only in the last

Establishment and content of sugars and phenols in Physalis callus obtained from different explants and concentrations of bap and naa - doi: 10.4025/actascibiolsci.v36i1.18074

Acta Scientiarum: Biological Sciences, 2013
Obtaining cells of Physalis pubescens is of interest for studies of primary and secondary metabolic pathways, in the search for new active molecules. Our objectives were to evaluate the regeneration potential of explants from different parts of the plant,

Mesenchymal cell invasion requires cooperative regulation of persistent microtubule growth by SLAIN2 and CLASP1

, 2016
Microtubules regulate signaling, trafficking, and cell mechanics, but the respective contribution of these functions to cell morphogenesis and migration in 3D matrices is unclear.

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-by-Cell Deconstruction of Stem Cell Niches [PDF]

Cell Stem Cell, 2020
Single-cell sequencing approaches offer exploration of tissue architecture at unprecedented resolution. These tools are especially powerful when deconvoluting highly specialized microenvironments, such as stem cell (SC) niches. Here, we review single-cell studies that map the cellular and transcriptional makeup of stem and progenitor niches and discuss

Effect of Pore Size on Cell Behavior Using Melt Electrowritten Scaffolds

Frontiers in Bioengineering and Biotechnology, 2021
Tissue engineering technology has made major advances with respect to the repair of injured tissues, for which scaffolds and cells are key factors. However, there are still some issues with respect to the relationship between scaffold and cell growth ...

Characterization of the Bronchoalveolar Lavage Fluid by Single Cell Gene Expression Analysis in Healthy Dogs: A Promising Technique

Frontiers in Immunology, 2020
Single-cell mRNA-sequencing (scRNA-seq) is a technique which enables unbiased, high throughput and high-resolution transcriptomic analysis of the heterogeneity of cells within a population.

Vinculin in cell–cell and cell–matrix adhesions [PDF]

Cellular and Molecular Life Sciences, 2017
Vinculin was identified as a component of focal adhesions and adherens junctions nearly 40 years ago. Since that time, remarkable progress has been made in understanding its activation, regulation and function. Here we discuss the current understanding of the roles of vinculin in cell-cell and cell-matrix adhesions.

MAP4K4 inhibition promotes survival of human stem cell derived cardiomyocyte and reduces infarct size in vivo [PDF]

, 2019
Heart disease is a paramount cause of global death and disability. Although cardiomyocyte death plays a causal role and its suppression would be logical, no clinical counter-measures target the responsible intracellular pathways. Therapeutic progress has
