<p>A technology capable of measuring cell-related reactions at a time within a wide range of concentration. Cell groups (200) are disposed in a cell-storing space (110) filled with liquid (120). A specific substance is supplied to the liquid in the cell-storing space (110) to form in the liquid (120) the concentration gradient (131) of the specific substance (130) extending from one end (111) of the cell-storing space (110) toward the other end (112). The cell groups in the cell-storing space (110) is picked up by an imaging device (320) and captured into an information processor, and image obtained by the information processor is divided into a plurality of regions along the above concentration gradient, feature amounts are extracted from image portions in respective regions, and information indicating the interrelation between the extracted feature amounts and the concentration gradient is created.</p> |
