Cell Polarization and Migration

Migration cellulaire
Migration cellulaire
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and ...
Polymérisation de l’actine et motilité cellulaire
Polymérisation de l’actine et motilité cellulaire
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. ...
Types de protubérances membranaires
Types de protubérances membranaires
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These ...
Mécanisme de formation des lamellipodes
Mécanisme de formation des lamellipodes
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or ...
Mécanisme de formation des Filopodia
Mécanisme de formation des Filopodia
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, ...
Migration des cellules cancéreuses par l’invasion des envahisseurs
Migration des cellules cancéreuses par l’invasion des envahisseurs
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are ...
Motilité cellulaire par Blebbing
Motilité cellulaire par Blebbing
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including ...
Rôle de la myosine dans la migration cellulaire
Rôle de la myosine dans la migration cellulaire
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common ...
Polarisation cellulaire par les protéines Rho
Polarisation cellulaire par les protéines Rho
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is ...
Chémotaxie et direction de la migration cellulaire
Chémotaxie et direction de la migration cellulaire
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, ...
Coordination cytosquelettique dans la migration cellulaire
Coordination cytosquelettique dans la migration cellulaire
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles ...
