Microfluidics in Cell Biology Part C, Volume 148, a new release in the Methods in Cell Biology series, continues the legacy of this premier serial with quality chapters authored by leaders in the field. Unique to this updated volume are three sections on microfluidics in various multi-cellular models, including microfluidics in cell monolayers/spheroids, microfluidics in organ on chips, and microfluidics in model organisms. Specific chapters discuss collective migration in microtubes, leukocyte adhesion dynamics on endothelial monolayers under flow, constrained spheroid for perfusion culture, cells in droplet arrays, heart on chips, kidney on chips, liver on chips, and more.
