  • Publication number: 20130030531
    Abstract: An improved bone graft is provided for human implantation, particularly such as a spinal fusion cage for implantation into the inter-vertebral space between two adjacent vertebrae. The improved spinal fusion cage includes a substrate block of high strength biocompatible material having a selected size and shape to fit the anatomical space, and a controlled porosity analogous to natural bone. The substrate block may be coated with a bio-active surface coating material such as hydroxyapatite or a calcium phosphate to promote bone ingrowth and enhanced bone fusion. Upon implantation, the fusion cage provides a spacer element having a desired combination of mechanical strength together with osteoconductivity and osteoinductivity to promote bone ingrowth and fusion, as well as radiolucency for facilitated post-operative monitoring. The fusion cage may additionally carry one or more natural or synthetic therapeutic agents for further promoting bone ingrowth and fusion.

  • Publication number: 20130017179
    Abstract: A cell population has been identified and isolated that can differentiate into multiple neuronal phenotypes, but cannot differentiate into glial phenotypes. This mammalian CNS neuron-restricted cell expresses highly polysialated or embryonic neural cell adhesion molecule (E-NCAM) and is morphologically distinct from neuroepithelial stem cells (NEP cells) and spinal glial progenitors derived from embryonic day 10.5 spinal cord. Methods for isolating these cells and uses thereof are also disclosed.

  • Publication number: 20120330420
    Abstract: An improved implant is provided for human implantation, such as a spinal implant for implantation into the intervertebral space between two adjacent vertebrae. Some embodiments include a substrate of high strength biocompatible material, such as doped silicon nitride ceramic for example. In some embodiments, the substrate may also include one or more regions of a controlled porosity analogous to natural bone. In other embodiments, the substrate may comprise the entire implant.

  • Publication number: 20120321705
    Abstract: A glial precursor cell population from mammalian central nervous system has been isolated. These A2B5+ E-NCAM? glial-restricted precursor (GRP) cells are capable of differentiating into oligodendrocytes, A2B5+ process-bearing astrocytes, and A2B5? fibroblast-like astrocytes, but not into neurons. GRP cells can be maintained by regeneration in culture. GRP cells differ from oligodendrocyte-type-2 astrocyte (O-2A) progenitor cells in growth factor requirements, morphology, and progeny. Methods of use of GRP cells are also disclosed.
