Protein phosphatase 1 activity promotes cohesive collective cell migration by restricting actomyosin contractility to the periphery of the collective and maintaining proper cadherin–catenin complex protein levels at cell–cell junctions.
Epithelia exhibit size-dependent growth dynamics caused by a decoupling between boundary and bulk cellular dynamics that enable robust expansion and drive cell cycling, collective migration, and tissue-spanning vortices.
Neural crest cells differentiated from patient-derived cells with mutations in the chromatin remodeler CHD7 show defective delamination, migration and motility in vitro, and defective migration in chick embryos.
Genetic and biochemical approaches identify a new component of the cellular signaling machinery driving migration of limb muscle precursor cells during mouse embryogenesis and reveal the underlying molecular mechanism.
Functional analysis of filopodia by specific interference with their formation and distribution reveals a critical role in conferring intracellular polarity and in controlling the dynamic properties of chemokine-guided cell migration in vivo.
