Abstract | OBJECTIVE: METHODS: KEY FINDINGS: Immunohistochemical staining in adult and fetal bone mirrors collagen I. PEDF localised to ridges of trabecular bone in tibial cortex and to megakaryocytes within bone marrow. Second, we observed that PEDF upregulates collagen I, HSP47 and MT1-MMP, while downregulating MMP-2 in osteosarcoma cells in vitro. CONCLUSION: PEDF is a promising antagonist to osteosarcoma cell metastasis via downregulation of MMP-2, and can induce tumour cells to further adopt differentiative properties, thereby possibly reducing their aggressive growth in vitro and in vivo.
