Visualization of the peripheral weave of microfilaments in glia cells.

A peripheral weave of microfilaments is visualized in human glia cells. In this weave small numbers of microfilaments converge to structures in the cell edge. Similar assemblies of microfilaments seem to be attached to structures on the surface of microspikes. Together with filaments splaying from the paracrystalline arrangement in microspikes, these units make up the peripheral weave. The filaments of the weave come in close contact with each other and with filaments of internal actin fibres.
