摘要: Pseudopodia, the cytoplasmic outgrowths of lamellar shape (lamellipodia, ruffles), filamentous (filopodia), or spherical (blebs), are “driving organs” formed by cells to spread and migrate, also can have sensory metabolic functions. The attachment lamellipodia filopodia extracellular matrix is achieved different types special adhesion structures, such as focal contacts (focal adhesions), complexes, fibrillar adhesions, hemidesmosomes, podosomes, invadopodia. dynamic properties regulation main contacts, play a pivotal role in cell migration. Other podosomes invadopodia, locally degrade components, thereby creating spaces for migration normal invasion malignant tumor cells.
