What is it about?

Human subjects are ideal for studying joint disease mechanisms and testing drugs, which, however, should not be used because of ethical issues. Therefore, we used human cells to generate tissues of the knee joint and built a miniature joint model on a chip device, called miniJoint, for this purpose.

Why is it important?

We found that the tissues could maintain their respective identities for at least four weeks in the miniJoint. Features of joint diseases could be modeled using the miniJoint platform, which also showed the ability to predict the efficacy of potential drugs targeting joint diseases.


We for the first time proved the feasibility of creating a four-tissue system that mimics key characteristics of healthy and diseased human synovial joints.
