title: [Contractile phenomena in a model nonmuscle system].
abstract: ATP--dependent contraction has been observed in cortices isolated from the dividing eggs of the pond snail and treated with fragments of the skeletal muscle myosin. The motive force of cytokinesis can be tentatively attributed to the enclosed cortical cytoskeleton which contains actinlike microfilaments organized in locally ordered clusters.
