How does force generation within lamellipodia facilitate cell translocation?
How does force generation within lamellipodia facilitate cell translocation? Interactions between actin filament networks and the focal adhesions to which they are linked results in the generation of forces. These forces may be exerted [...]
What mechanisms drive retraction of the trailing edge?
What mechanisms drive retraction of the trailing edge? Protrusion at the front and retraction at the rear are key force-generating processes at the cell periphery that culminate in the translocation of the cell. For [...]
What are invadopodia?
What are invadopodia? Invadopodia are actin-rich structures that are present at the basal surfaces of cells that are capable of crossing extracellular barriers, such as cancer cells. The primary function of invadopodia appears to [...]
What are the functions of podosomes?
What are the functions of podosomes? Both focal adhesions and podosomes are intimately involved in cell motility, with podosomes specifically implicated in cell invasion. Invasiveness is achieved through the secretion of matrix metalloproteinases (MMPs) [...]
What are podosomes?
What are podosomes? Podosomes are actin-rich, adhesive structures that are present at the ventral surface of cells of the monocytic myeloid lineage, stimulated endothelial cells [1] and cultured Src-transformed cancer cells. These structures are [...]
What are the first steps in invadopodia assembly and disassembly?
What is the first step in invadopodia assembly? Initiation of invadopdia formation is highly complex, being influenced by various signalling cascades and phosphorylation events that occur following detection of a stimulant. For example, activation [...]
