CULTURE VESSELS CONTAINING 3D CELL CULTURE SUBSTRATES WITH DIFFUSION STRUCTURES

A cell culture device comprises a multi-well cell culture plate comprising a plurality of wells, each well comprising a top, a bottom, and a sidewall disposed between the top and the bottom and having an interior surface comprising an ultra-low attachment surface. A plurality of scaffolds are disposed within wells of the multi-well cell culture plate, each scaffold comprising a cell-adherent surface. In some embodiments, the scaffold comprises a fiber scaffold. In some embodiments, the scaffold comprises an artificial vascular scaffold. In some embodiments, cell culture devices comprise a plurality of hydrogel scaffolds disposed in a multi-well cell culture plate, the plurality of hydrogel scaffolds comprising hydrogel fibers of differing lengths, wherein opposite ends of a hydrogel fiber are disposed in different wells within the multi-well cell culture plate to create interconnected wells.
