title: [Bioelectrical properties and ultrastructure of vascular smooth muscle cells in tissue culture].
abstract: Intracellular recording was performed in tissue culture of the rabbit vena portae from the smooth muscle cells (SMC) with spontaneous discharges. In inactive SMC the dischartges could be elicited by hyperpolarizing current. The membrane potentials and the input impedance of the SMC decreased with the growth of osmolarity of extracellular medium. The cells were identified as those of smooth muscle on the ground of electronmicroscopic studies. Cellular contacts of nexus type existed between adjacent SMC.
