OPEN-WELL MICROCAVITY PLATE

Cell culture devices comprise a frame comprising an open well disposed therein and a fluid inlet area in communication with the open well. The open well comprises a top opening, a bottom plate comprising a microcavity substrate, the bottom plate defining a major surface, and one or more sidewalls extending from the bottom plate to the top opening. The microcavity substrate comprises a plurality of microcavities, and each microcavity is configured such that cells cultured in the well form a spheroid. The cell culture device may be a reservoir open well microcavity plate used for spheroid cell culture.
