     cartilage tissue engineering can provide substantial relief to people suffering from degenerative cartilage disease, such as osteoarthritis. the autologous platelet-rich plasma (prp) application appears to improve cartilage healing due to its ability to positively influence cellular mechanisms, mainly in cells from synovium and cartilage. primary cultures of human synovial fluid stem cells (synoviocytes, scs) and chondrocytes (ccs) were exposed to various concentrations of non-activated prp and plateletpoor plasma (ppp) prepared by apheresis. cell proliferation and migration were evaluated in real-time with the non-invasive xcelligence system. it was found that prp had a similar effect on the growth of cells as fetal bovine serum (fbs). surprisingly, our proliferation assay results indicated that 50% ppp had the largest effect on both cell types, with a statistically significant increase in cell number (p<0.001) compared to the (0% fbs) in vitro control. the migratory ability of scs was significantly enhanced with 10% prp and 0.8% hyaluronic acid (ha). ha also augmented migration of ccs. in summary, these results demonstrate that directed cell proliferation and migration are inducible in human articular ccs and scs, and that both platelet-derived fractions may exert a positive effect and modulate several cell responses that are potentially involved in tissue integration during cartilage repair.
