The complex interactions of cells with extracellular matrix (ECM) play crucial roles in mediating and regulating many processes, including cell adhesion, migration, and signaling during morphogenesis, tissue homeostasis, wound healing, and tumorigenesis. Many of these interactions involve transmembrane integr...

"3D-matrix adhesions" differ from focal and fibrillar adhesions characterized on 2D substrates in their content of alpha (5)beta (1) and alpha (v)beta (3) integrins, paxillin, other cytoskeletal components, and tyrosine phosphorylation of focal adhesion kinase (FAK). Relative to 2D substrates,...
Adhesion to the extracellular matrix persists during mitosis in most cell types. However, while classical adhesion complexes, such as focal adhesions, do and must disassemble to enable mitotic rounding, the mechanisms of residual mitotic cell–extracellu

We focus on the complement of proteins each adhesion complex recruits to bear the force and the signal transduction pathways activated to allow the cell to tune its contractility. A discussion of the similarities, differences, and crosstalk between cadherin- and integrin-mediated force transmission is...
16. These differences could also be attributed to just a few amino acid differences in the sequences of the two receptors15. Our results suggest that though there are differences in signaling between the rat and human receptors, these differences did not extend to cell–matrix adhesion, which ...
