Abstract

Methods and systems for cell media exchange wherein media maybe aspirated without also aspirating cells and wherein removal and re-plating of cells is not necessarily required. For example, the cell culture system or apparatus features a gap that is small enough to retain cells therein and also sized to prevent media from leaking. The methods and systems of the present invention may help reduce stress and damage to cells as compared to traditional methods that require removing and re-plating cells.
