SERCA regulates collective cell migration by maintaining cytoplasmic Ca2+ homeostasis

Characterized by multicellular migratory behavior and cooperative ability,collective cell migration plays critical roles in developmental,physiological and pathological processes,such as organogenesis,wound healing and tumor metastasis (Friedl and Gilmour,2009).Molecular features of collective cell migration including collective polarization,coordinated cytoskeletal activity,and guidance signaling have been recently investigated in a variety of in vivo and in vitro model systems (Scarpa and Mayor,2016),but many other aspects of regulatory mechanisms remain unexplored.
