In vitro cell culture device including cartilage and methods of using the same

摘要

The present invention relates to an in vitro cell culture device which includes a vessel comprising an inner surface, a layer of cartilage disposed on at least a portion of said inner surface, the layer of cartilage including a plurality of chondrocytes in an extracellular matrix, and a growth medium in the vessel, the layer of cartilage being bathed in the growth medium. Also disclosed is a composite cell culture prepared from the in vitro cell culture device, the composite cell culture includes a first layer including chondrocytes in an extracellular matrix, a second layer disposed on the first layer and including type I collagen, and a third layer disposed on the second layer and including cells at least partially covering the second layer. Further aspects of the present invention relate to methods of preparing an in vitro composite cell culture, methods of screening putative therapeutic agents for activity in promoting re-epithelialization of cartilaginous tissues, and methods of screening putative therapeutic agents for activity in inhibiting growth factors or proteinases.
