["Spontaneous" oscillations of the cell surface in the frequency interval of 0.2-30 Hz].
1989
The local transverse displacements of the cell surface within the frequency range of 0.2-30 Hz occur on animal cells attached to cover glass: fibroblasts 3T6, primary culture of rat cardiomyocytes, mouse lymphocytes, human macrophages and erythrocytes, frog erythrocytes. The area of the cell rim, moving transversely, is no more than 0.5 X 0.5 microns. The maximum amplitude of the local transverse surface displacement is different in various cell types, being maximum (350-400 nm) in human erythrocytes and minimum in fibroblasts 3T6, mouse lymphocytes and human macrophages (20-30 nm). High-amplitude oscillations of human erythrocytes and low-amplitude oscillations of frog erythrocytes correlate with differences in the size of elastic shear modulus.
