title: [Changes in the surface morphology of normal and transformed mouse fibroblasts following disruption of cell-substrate adhesion].
abstract: By means of scanning electron microscopy surface morphology of cultured normal mouse embryo fibroblasts (MEF) and transformed mouse fibroblasts of L strain was studied in the course of alteration of cell-substrate adhesion with proteases, EDTA and urea. The morphology of cell rounding induced by the above agents in MEF and L cells was almost independent on the type of the agent. The rounding of MEF proceeded through three stages and was accompanied by substantial changes of cell surface relief. L cells lacked the intermediate stage (formation of thick processes) during their rounding which proceeded without any changes of cell surface relief. It is suggested that the observed differences are related to the poorer development of the lamelloplasm and microfilaments bundles in the transformed cells ascompared to the normal ones.
