  Definition: Phagocytosis is a specific form of endocytosis involving the vesicular internalization of solid particles, such as bacteria. It is therefore distinct from other forms of endocytosis such as pinocytosis, the vesicular internalization of various liquids, and recptor-dependent endocytosis.
  Phagocytosis involves three distinct but interrelated steps:
  (1) recognition and attachment of the particle to be ingested by the leukocyte;
  (2) its engulfment, with subsequent (...)

  Cells utilize actin filaments to produce protrusive and contractile arrays that cooperate to drive cell motility.
  The generation of the two arrays and the coupling between them result from the unique properties of the lamellipodium, a protrusive leaflet of cytoplasm at the cell edge.
  From the lamellipodium into the lamella behind, there is a transition from a fast retrograde flow of actin polymer driven by polymerization to a slow flow driven by the interaction of anti-parallel arrays of (...)

  Process by which the daugther cells separate from each other at the end of the cellular division
  Cytokinesis follows nuclear division and generates two distinct daughter cells, each replete with a full complement of the genome and cytoplasmic organelles.
  Completion of cell division during cytokinesis requires temporally and spatially regulated communication from the microtubule cytoskeleton to the actin cytoskeleton and the cell membrane.
  Exit from the cytokinetic phase of the cell cycle (...)
