Precise frictional characteristics of the red blood cells (RBCs) have not been understood. Hayase et al. developed the inclined centrifuge microscope, and the frictional characteristics of RBCs on a glass plate were measured at the first step. In that research, it was the subject of discussion whether the cells glide or roll on the glass plate since the resolution of the microscope was not sufficient to distinguish the cell motion. This report deals with improvement of the observation technique for cell motion. At first, the magnification of the inclined centrifuge microscope is increased by 5 times. The shape of RBCs under movement can be seen clearly and cells seem to glide on the glass plate. However, it is still difficult to exclude the possibility of cell rolling. So authors investigated microbeads as the indicator of cell motion. It revealed that ordinary microbeads are too small to observe, and they don't adhere to RBCs.
