Microfluidics in Cell Biology Part B: Microfluidics in Single Cells, Volume 147, a new volume 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 single cell models, including microfludics in micro-organisms, microfluidics for cell culture and cell sorting of mammalian cells, and microfluidics for cell migration. Specific sections in this latest release include Temperature control and drug delivery for cell division cycle control in fission yeast H2O2 stress response in budding yeast, Antibiotic resistance in bacteria, Metabolism in bacteria, Fluidized beds for bacterial sorting and amplification, Microfluidics for cell culture and cell sorting of mammalian cells, Hydrogel microwells, Immune cells migration in complex environments, Neutrophiles migration in health and disease, Cell guidance by physical cues, Stable gradients in gels of extracellular matrix for cancer cell migration, and more.
