How do filopodia move dynamically?
What causes filopodia retraction and collapse? Binding of filopodia to certain ligands or substratum may hinder filament assembly, thereby leading to changes that promote retraction, collapse or growth cone turning [1][2]. For example, substrate [...]
What is the role of the lamellipodia in mechanosensing and cell motility?
What is the role of the lamellipodia in mechanosensing and cell motility? During cell migration, and in the absence of filopodia, lamellipodia detect the stiffness of the surrounding ECM in a process called rigidity [...]
What steps are involved in Lamellipodia assembly?
What steps are involved in Lamellipodia assembly? The lamellipodia is a distinct region of the cell that facilitates cell motility and various mechanosensing mechanisms. Lamellipodium assembly can be described in a series of defined [...]
How does nucleation of actin initiate lamellipodia formation?
How does nucleation of actin initiate lamellipodia formation? In the first phase of lamellipodia formation, actin filament polymerization produces a protrusive force on the cell membrane that promotes the spreading out and enlargement of [...]
What mechanisms drive extension, pause and stasis of the lamellipodia?
What mechanisms drive extension, pause and stasis of the lamellipodia? Extension of the newly formed actin filament branches occurs at the interface between the leading edge and the existing actin filament network [1] and [...]
How do focal adhesions act as molecular clutches in lamellipodia?
How do focal adhesions act as molecular clutches in lamellipodia? Once formed, focal adhesions essentially act as “molecular clutches”, promoting protrusion at the leading edge whilst suppressing membrane contraction (reviewed in [1] [2][3]). Adhesions [...]
