Title:
METHOD OF MEASURING CELL MOTILITY AND SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2007/066684
Kind Code:
A1
Abstract:
It is intended to provide a technique whereby quantitative data of cellular chemotactic activity can be obtained. Namely, a method of measuring cell motility whereby the motility state of cells is measured. Vital cells are located in an observation space (100) in such a state as allowing the movements of the cells on a plane. A stimulant affecting the cell motility is administered to the observation space (110) and then at least one of the following factors is measured: (a) the reaction time required from the administration of the stimulant until the movement starts for each cell; and (b) the movement-duration time for each cell that has started the movement.
