Our ability to accurately predict how humans respond to drugs during clinical trials is limited due to the lack of physiologically relevant preclinical models. This microphysiological system can address that disparity. This human cell derived syst

Resumen

We provide detailed methods for generating four types of tissues from human mesenchymal stem cells, which are used to recapitulate the cartilage, bone, fat pad, and synovium in the human knee joint. These four tissues are integrated into a customized bioreactor and connected through microfluidics, thus generating a knee joint-on-a-chip.
