Platelet derived growth factor-AB enhances knee meniscal cell activity in vitro
چکیده انگلیسی

Meniscal healing especially in the inner avascular region has always been a major challenge. In this study we investigated the potential for platelet derived growth factor-AB (PDGF-AB) to promote meniscal tissue regeneration in the inner (avascular), middle, and outer (vascular) zones of the meniscus. Various concentrations of PDGF-AB were tested on sheep meniscal cell cultures. We used the radioactive thymidine uptake assay to assess cell proliferation, and the radioactive sulphur and proline uptake assays and Blyscan assay to assess matrix formation. In general, PDGF-AB stimulated both cell proliferation and matrix formation by cells from all meniscal zones. PDGF-AB at a concentration of 100 ng/ml increased cell proliferation and matrix formation by eight and four fold respectively, by fibrochondrocytes cultured from all meniscal zones (p < 0.001). These results indicate that fibrochondrocytes present within the avascular region of the meniscus have the ability to proliferate and form new matrix when exposed to anabolic cytokines such as PDGF-AB.
