Collective cell migration is a key driver of embryonic development, wound healing, and some types of cancer invasion. Here we provide a physical perspective of the mechanisms underlying collective cell migration. We begin with a catalogue of the cell-cell and cell-substrate interactions that govern cell migration, which we classify into positional and orientational interactions. We then review the physical models that have been developed to explain how these interactions give rise to collective cellular movement. These models span the sub-cellular to the supracellular scales, and they include lattice models, phase fields models, active network models, particle models, and continuum models. For each type of model, we discuss its formulation, its limitations, and the main emergent phenomena that it has successfully explained. These phenomena include flocking and fluid-solid transitions, as well as wetting, fingering, and mechanical waves in spreading epithelial monolayers. We close by outlining remaining challenges and future directions in the physics of collective cell migration.

“…Some of the earliest indications first arose from surgical transplantation experiments designed to exploit pigment variations in amphibian embryos. Around the beginning of the 20th Century, embryologists such as Born (), Harrison (), and Spemann () pioneered the use of chimeras, that is combining embryonic components from distinct animal species, to follow the movements and fates of cells, and understand the inductive properties of tissues (Harrison, ; Mangold, ; Mangold & Seidel, ; Noden, ; Spemann, ; Spemann & Mangold, ). Their reliance on intrinsic differences in the number, distribution, and color of intracellular pigment granules as a means to keep track of donor versus host tissues was actually a proxy for a neural crest‐derived lineage (i.e., melanocytes), something which was suggested by Harrison () and others but which remained debatable at the time (Dorris, ; DuShane, ; Harrison, ; Holtfreter, ; Raven, ).…”

Neural crest and the origin of species‐specific pattern

SummaryFor well over half of the 150 years since the discovery of the neural crest, the special ability of these cells to function as a source of species‐specific pattern has been clearly recognized. Initially, this observation arose in association with chimeric transplant experiments among differentially pigmented amphibians, where the neural crest origin for melanocytes had been duly noted. Shortly thereafter, the role of cranial neural crest cells in transmitting species‐specific information on size and shape to the pharyngeal arch skeleton as well as in regulating the timing of its differentiation became readily apparent. Since then, what has emerged is a deeper understanding of how the neural crest accomplishes such a presumably difficult mission, and this includes a more complete picture of the molecular and cellular programs whereby neural crest shapes the face of each species. This review covers studies on a broad range of vertebrates and describes neural‐crest‐mediated mechanisms that endow the craniofacial complex with species‐specific pattern. A major focus is on experiments in quail and duck embryos that reveal a hierarchy of cell‐autonomous and non‐autonomous signaling interactions through which neural crest generates species‐specific pattern in the craniofacial integument, skeleton, and musculature. By controlling size and shape throughout the development of these systems, the neural crest underlies the structural and functional integration of the craniofacial complex during evolution.
