Abstract

Electrical oscillatory rf phenomena are present during the division of cells. These were examined by studying the attraction of cells for polarizable powders. They are understood to occur by a process termed microdielectrophoresis (micro-DEP), the motion induced by a nonuniform electric field acting on a polarizable body. The suggestion that an electrical oscillatory aspect may also be involved in the "contact" or density inhibition of cell division and the mechanisms that may cause invasiveness of oncogenic cells are theoretically explored (i.e., changes in either the power level or the frequency of the oscillatory phenomena associated with cell division, or in the degree of electrical insulation of the cell from electrical damping by nearby cells). A number of experiments to test this hypothesis are suggested.

摘要

在细胞分裂过程中存在电振荡射频现象。通过研究细胞对可极化粉末的吸引力来对这些现象进行检测。据认为,它们是通过一种称为微介电泳(micro-DEP)的过程发生的,即作用于可极化物体上的非均匀电场引起的运动。从理论上探讨了电振荡方面可能也参与细胞分裂的“接触”或密度抑制以及可能导致癌细胞侵袭性的机制(即与细胞分裂相关的振荡现象的功率水平或频率的变化,或细胞与附近细胞的电阻尼的电绝缘程度的变化)。提出了一些实验来检验这一假设。
