title: Microfilament distribution in cold-treated Drosophila embryos.
abstract: Cold treatment of Drosophila embryos is observed to result in general alteration of microfilament distribution leading to deformation of the surface caps and to perturbation of the process of cleavage furrow extension. After exposure to low temperature the cortical actin caps underwent several morphological changes, despite the arrested nuclear cycle. These observations are discussed in relation to centrosome behavior during the cell cycle.
