Abstract: Described herein is a cell culture system for constructing a perfusable network of self-assembled cells comprising a multi-well plate embedded with microchannels connecting a central well with at least one inlet well and at least one outlet well, the central well for culturing seeded cells within an extracellular matrix, wherein the perfusable network allows perfusion through the microchannels connecting the central well with at least one inlet well and at least one outlet well. The cell culture system allows the array of perfusable networks formed, connected, and perfused inside the multi-well plate to be accessible and/or extractable from the top of the central well. In aspect, the cell culture system can improve the experimental throughputs of organ-on-a-chip systems and expand the application of microphysiological systems to regenerative cell therapy. A perfusable network of self-assembled cells and method of making thereof using the cell culture system described herein are also provided.
