National Center for Biotechnology Information WebWhat is the difference between focal adhesions and Hemidesmosomes? Cells attach to the underlying extracellular matrix through two types of integrin-dependent junctions: focal adhesions, which attach the actin cytoskeleton to fibers of fibronectin, and hemidesmosomes, which connect intermediate filaments to basal laminae (Figure 22-9).

WebFocal adhesions are consistently found at the end of stress fibers and are therefore highly integrated with the bulk of the cytoskeleton. Consequently, focal adhesions serve to transmit force, internally generated by the cytoskeletal network, to the ECM and vice versa via adhesion receptors [12]. WebNov 18, 2024 · As focal adhesions and ECM–receptor interaction pathways were perturbed after PAXIP1-AS1 knockdown, we also investigated its role in migratory processes. As observed in a scratch wound healing assay, both knockdown approaches of PAXIP1-AS1 resulted in a marked reduction in the migratory potential of PASMCs (Figure 4 D,E).
