Correlation between the Electrical Properties and Morphological Characteristics in the Smooth Muscle Cells during Culture

  • T. Maruyama


Electrophysiological properties of smooth muscle cells have been extensively studied in various smooth muscle tissues. These distinct membrane properties of smooth muscle cells are based on the studies of organic tissues. Studies on the electrical properties of the smooth muscle cells from intact tissues raise certain problems because of the neural elements within the tissues, and because of the low electrical coupling between the smooth muscle cells. Furthermore, the presence of diffusion barriers and the intercellular current make it impossible to measure accurately the electrical properties of a single smooth muscle cell. To overcome such problems, researchers have described electrophysiological measurements on the cultured smooth muscle cell in vitro (1, 2, 3, 4 and 5). We re-investigated the cultured smooth muscle cells from guinea-pig taenia coli to elucidate the electrical properties of cultured smooth muscle cells.
