| Research Abstract |
From the point of wound healing view, it is important to analyze the repair process of artificially inflicted damages to a live cell. We employed a small glass bead glued at the end of a thin tip of atomic force microscope and coated with enzyme with cell membrane hydrolyzing activity. When the glass bead touched the cell surface, it created a small hole on the cell membrane. First we studied the correlation between the time of repair of the hole and the hole diameter. We noticed that a certain time is required before repair process effectively started. We also noticed that bubble like structures were formed on the cell surface (blebs) and studied the growth and retraction process of them. We also studied the repair process of the damages given to intracellular stress fibers.
