We continue to work to develop pure and stable cultures of primary human cells derived from our commercially available Mesenchymal Derived stem cells; including our human chondrocytes. These cells produce collagen and are critical to proper joint function.  Joint disease and injury often involve defects in collagen production and/or damage to chondrocytes due to inflammation, disease or injury. This makes them excellent for use in the basic research and development  of therapies for diseases of the joint.
