    Neonatal chimerization with human glial progenitor cells can both remyelinate and rescue the otherwise lethally hypomyelinated shiverer mouse.

    H9 cells WA; passages 30 to 41 were grown on mitotically inactivated mouse embryonic fibroblasts essentially as described in [ 17 ]. Panel B shows representative morphologies of hOPCs on days 3, 7, 12, 17, 23, 27, 41, 90 and 97 that roughly correspond to milestones in A.

    Chronically increased ciliary neurotrophic factor and fibroblast growth factor-2 expression after spinal contusion in rats. Electron microscopy revealed that mature transplant-derived oligodendrocytes ensheathed host axons with spiral wraps intimately associated with myelin sheaths.

    Differentiation of human oligodendrocytes from pluripotent stem cells.

    This pattern suggests that, at the time points studied here, surviving cells are not proliferative at the original transplant site or in their migratory paths and destinations Fig.

    Injection of adult neurospheres induces recovery in a chronic model of multiple sclerosis. Arrows denote human oligodendrocyte progenitor cell distribution.

    Given the very low level of proliferation of transplanted cells as early as 6 weeks post-transplantation and their prompt differentiation into mature oligodendrocytes, the possibility of overgrowth and, hence, tumorigenic risk is very low. Brain Pathol.

    Insets in d-i are magnifications of cells or groups of cells labeled with asterisks to showcase typical cytologies and immunoreactivities, including nuclear h and non-nuclear d,e,f,g,i localizations. In the present experiments, we employed a severe TBI regimen using a g weight that was freely dropped onto the steel disc through a Plexiglass tube from a height of 2 meters.

    In our hands, the method of Hu and colleagues appeared to be more successful in generating viable transplants, although this observation was not confirmed in a systematic fashion.

Traumatic axonal injury in impact acceleration-injured nude rats as demonstrated by Gallyas silver staining. In the gray matter away from the injection site ipsilateral or contralateralcytology was mixed.

    Distance between migrating cells in section 9 and edge of transplantation site section 4 is 4.

    Impaired axoplasmic transport is the dominant injury induced by an impact acceleration injury device: an analysis of traumatic axonal injury in pyramidal tract and corpus callosum of rats.

    Numbers of surviving hOPCs were counted in serial, systematically and randomly sampled coronal sections based on the optical fractionator concept with the aid of a motorized stage Axioplan microscope Carl Zeiss Inc. CAS Google Scholar On day 84, spheres were trypsinized and plated on p-L-ornithine and laminin-coated plates and coverslips and cultured for 2 weeks in the same medium for transplantation or immunocytochemistry, respectively.
