Visualization of the peripheral weave of microfilaments in glia cells
Abstract:
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.
Insights
A peripheral weave of microfilaments was visualized in human glia cells, revealing their convergence at the cell edge and attachment to microspikes. This structure interacts closely with internal actin fibers, offering new insights into glial cell architecture.
