New Force Sensing Method Reveals How Cells Sense Tissue Stiffness
To measure the exerted molecular forces, researchers engineered two novel fluorescent biosensors that change their color in response to piconewton forces. By applying the method to the cell adhesion protein talin, they discovered the central mechanism that allows cells to feel their mechanical environment.

MMP14 as a Novel Downstream Target of VEGFR2 in Migratory Glioma-Tropic Neural Stem Cells
The authors investigated the mechanisms of tumor-tropic migration of an FDA-approved neural stem cell (NSC) line by performing a gene expression analysis. They identified vascular endothelial growth factor-A (VEGFA) and membrane-bound matrix metalloproteinase (MMP14) as molecules whose expression are significantly elevated in migratory NSCs.

Jararhagin Disruption of Endothelial Cell Anchorage Is Enhanced in Collagen Enriched Matrices
Investigators used two-dimension (2D) or three-dimension (3D) cultures of HUVECs on matrigel and observed the same characteristics as in ex vivo experiments: only the hemorrhagic toxin was able to localize on surfaces or internalize endothelial cells in 2D cultures or in the surface of tubules formed on 3D cultures. The contribution of matrigel, fibronectin and collagen matrices in jararhagin-induced endothelial cell damage was then analyzed. [Toxicon] Abstract
REVIEWS
Extracellular Matrix Component Signaling in Cancer
In the environment of tumors, there may be changes in cell populations and their receptor profiles as well as matrix constitution and protein cross-linking. The authors summarize roles of the three major matrix receptor types, with emphasis on how they function in tumor progression. [Adv Drug Deliv Rev] Full Article
Pharmacology of the Cell/Matrix Form of Adhesion
The author focuses on cell/integrin adhesion based on two specific integrins, α5β1 and αvβ3, activated by the preferential binding of fibronectin, a unique extracellular matrix protein. [Pharmacol Res] Abstract
