Much of what we know about the mechanisms of cell migration stems from in vitro studies with 2D substrates (Friedl and Alexander, 2011; Mogilner and Oster, 1996; Pollard and Borisy, 2003). The classical model of cell migration along 2D planar surfaces is characterized by cycles of actin polymerization-driven lamellipodial protrusion, integrin-dependent adhesion, myosin II-mediated contraction, and de-adhesion at the trailing edge. Although 2D migration is relevant in certain processes, such as neutrophil migration along the endothelium or epithelial cell wound healing, most 2D assays fail to recapitulate the physiological tissue environment encountered in vivo (Wirtz et al., 2011). Cells often migrate in vivo within 3D extracellular matrices (ECMs). Cells also migrate through 3D longitudinal tracks with bordering 2D interfaces (i.e., channels). These channels…

Eluted cell-surface protein was analyzed using European blot analysis then. To remove the 155-kDa hERG proteins for the cell surface area, hERG-HEK cells cultured in 5 or 0 mm K+ moderate were treated with proteinase K (PK). range stably expressing hERG stations (hERG-HEK cells) was supplied by Dr. Craig January (College or university of Wisconsin-Madison); cDNA was supplied by Dr. Gail Robertson (College or university of Wisconsin-Madison). plasmids had been from Addgene aswell as from Dr. Terry Hbert (McGill College or university, Montreal). Cells had been maintained in minimum amount essential moderate (MEM) supplemented with Elf1 10% fetal bovine serum (FBS), 1% nonessential proteins, and 1% sodium pyruvate (Invitrogen). For 0 mm K+ culture-induced hERG internalization, we utilized a custom made 0 mm K+ MEM that does not have K+ in virtually any type but contains all the components of regular MEM (Invitrogen). Because FBS consists of K+, FBS had…
