    摘要: Methods and compositions are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The administration of soluble complement inhibitor molecules to body fluids prevents the complement mediated inactivation of the retroviral vector particles, and provides a safety mechanism for such gene therapy procedures, as the action of soluble complement inhibitors is transient, and any retroviral vector particles present after the return of uninhibited complement activity will be inactivated. Preferred soluble complement inhibitors for use in the practice of the present invention include complement inhibitory anti-complement component mAbs (including complement inhibitory anti C5 antibodies).

    摘要: Modified retroviral vector particles and modified retroviral producer cells producing such particles are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The modifications involve genetic alterations to effect the expression by these cells and particles of complement inhibitor activity. The genetic alterations involve the introduction of nucleic acid expression constructs directing the expression of retroviral SU(gp70)/complement inhibitor chimeric proteins into cells from which the producer cells are derived.

    摘要: A temperature regulated hybridization chamber which includes an outer container which defines a first chamber for receiving a first fluid having a predetermined temperature. The hybridization chamber includes an inner container having a generally horizontal bottom wall with a periphery and an inner container side wall extending generally upwardly from the periphery of the inner container bottom wall. The inner container bottom wall and the inner container side wall define a second chamber for receiving a second fluid. The inner container is positioned within the first chamber with the inner container bottom wall and the inner container side wall being spaced from the outer container bottom wall and the outer container side wall, respectively, such that when the first fluid is positioned within the first chamber the first fluid is in engagement with the inner container bottom wall and inner container side wall. A drain conduit is in fluid communication with the second chamber for removing the second fluid from the second chamber. The drain conduit is positioned such that the second fluid flows through the drain conduit due to the force of gravity such that the second fluid in the inner chamber is maintained at a temperature which is about equal to the predetermined temperature of the first fluid.

    摘要: A method for enhancing and/or increasing the efficiency of repair of tissues, primarily bone or cartilage, using genetically engineered cells has been developed. In the preferred embodiment, mesenchymal stem cells are isolated from periosteum tissue, and transfected with the gene encoding a growth factor for the particular cell type to be repaired. For example, for repair of bone, a gene (or genes) encoding bone morphogenic protein is transfected into periosteal cells. The transfected periosteal cells then express the bone morphogenic protein in culture to promote bone repair as a function of the expressed bone morphogenic protein. Cells can be transfected using any appropriate means, including viral vectors, as shown by the example, chemical transfectants, or physico-mechanical methods such as electroporation and direct diffusion of DNA. Genes can encode any useful protein, for example, a specific growth factor, morphogenesis factor, a structural protein, or a cytokine which enhances the temporal sequence of wound repair, alters the rate of proliferation, increases the metabolic synthesis of extracellular matrix proteins, or directs phenotypic expression in endogenous cell populations. Representative genes encoding proteins include bone growth factor genes, cartilage growth factor genes, nerve growth factor genes, and general growth factors important in wound healing, such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF-1), epidermal growth factor (EGF), basic fibroblast growth factor (FGF), endothelial derived growth supplement.

    摘要: A vector particle (eg., a retroviral vector particle) containing a chimeric envelope includes a receptor binding region that binds to a receptor of a target cell. The receptor of the target cell is other than the amphotropic cell receptor. The receptor binding region may be a receptor binding region of a human virus. A portion of the envelope gene may be deleted and the deleted portion is replaced with another receptor binding region or ligand. Such vector particles are targetable to a desired target cell or tissue, and may be administered directly to the desired target cell or tissue as part of a gene therapy procedure, or administered directly into the patient.
