Podosome-type adhesions and focal adhesions, so alike yet so
... Focal complexes are 0.5-1 µm dot-like contacts localized along the lamellipodia. These structures are not connected to stress fibers although they have been shown to be linked to the actin network. Moreover, they do not contain Zyxin suggesting that they are subjected to moderate mechanical tensions ...
