Actin cytoskeleton of human platelets activated on CRP-coated surfaces.

Cytoskeleton of a human platelet activated on a CRP-coated coverslip surface by electron microscopy. Human platelets were activated on a CRP-coated coverslip surface. Cells were permeabilized with Triton X-100 in PHEM buffer, rapidly frozen, freeze-dried, and metal-coated. Cytoskeletons have prominent central regions from which motile filopodia extend.
