It is intended to provide a well unit to be used in fabricating an apparatus whereby movements of cells based on their own power can be accurately and easily detected in order to detect cell chemotaxis due to a chemotactic factor or inhibition of cell chemotaxis by an inhibitor. Namely, a well unit to be used in an apparatus for detecting cell chemotaxis and separating cells characterized in that a plural number of wells, in which a liquid sample can be contained in a static state, are connected to each other via channels, the channels are provided with banks, and in the upper part of the banks, one or more grooves having a width and/or a depth fit for the size or deformability of cells are formed, or a plane is formed in such a manner that there is a space between the plane and a glass substrate having a depth fit for the size or deformability of the cells. |
