In a recent study from October 2007, a group from China was the first to document platelet rich plasma’s ability to support chondrogenesis (cartilage cell growth). They took cartilage from the rabbit’s ear, & mixed it with PRP and calcium chloride & thrombin (to form a matrix). Two months later, hard knobbles were found and seen on MRI, as well as histological analysis (cellular) and staining confirmed cartilage growth. Interestingly, there was no cartilage growth with the control group that received PRP alone. This study demonstrated successful formation of new cartilage with an injectable graft using PRP and cultured chondrocytes.
