Inflammation aggravates brain injury caused by stroke and neurodegeneration. Osteopontin (OPN) is a cytokine-like glycoprotein that binds to various integrins and CD44 variants. OPN exerts proinflammatory effects in autoimmune conditions but also has cytoprotective properties and participates in wound healing. In this study, we addressed the role of OPN in(More)
Transected axons can regenerate beyond the site of injury in the peripheral but not in the central nervous system (CNS). Increasing evidence implicates inflammatory processes as modulators of axon regeneration after injury. In this study, we addressed a possible role of the matricellular glycoprotein osteopontin (OPN) using crush lesions of the optic and(More)
Hematopoietic bone marrow stem cells generate differentiated blood cells and, when transplanted, may contribute to other organs, such as the brain, heart, and liver. An understanding of in vivo clonal behavior of stem cells will have important implications for cellular and gene therapy. For the first time, we have directly demonstrated the derivation of(More)
Retroviral insertion site analysis was used to track the contribution of retrovirally transduced primitive progenitors to hematopoiesis after autologous transplantation in the rhesus macaque model. CD34-enriched mobilized peripheral blood cells were transduced with retroviral marking vectors containing the neo gene and were reinfused after total body(More)
Axon regrowth after nerve injury can occur in the peripheral but fails in the central nervous system. Cellular reactions at the lesion site affect axonal regrowth. We compared gene regulation in optic nerve (ON) and sciatic nerve (SN) crush lesions in adult rats by cDNA array analysis, quantitative RT-PCR and immunohistochemistry, focusing on the primary(More)
