Abstract

The present invention is directed to a method of measuring cell migration by measuring the invasion ratio of cells incubated on a pillar array inserted into a well structure, the method including steps of: preparing a pillar array having a plurality of micropillars and a well structure having a plurality of microwells into which the plurality of micropillars is insertable, respectively; forming cell spheroids by incubating cells in an extracellular matrix attached to the end contact surfaces of the micropillars; allowing the cells contained in the cell spheroids to invade the end contact surfaces; staining and scanning the cell spheroids, the cells contained in the cell spheroids, and the cells that invaded the end contact surfaces; and calculating the invasion ratio of cells by the following equation through a fluorescence image of the scanned cells: wherein Arepresents the total cell area, and Arepresents the spheroid area.
