The upregulation of genes normally associated with development may occur in the adult after spinal cord injury (SCI). To test this, we performed real-time RT-PCR array analysis of mouse spinal cord mRNAs comparing embryonic day (E)14.5 spinal cord wi

The adult spinal cord contains a pool of endogenous glial precursor cells, which spontaneously respond to spinal cord injury (SCI) with increased proliferation. These include oligodendrocyte precursor cells that express the NG2 proteoglycan and can d

The close homolog of the adhesion molecule L1 (CHL1) is important during CNS development, but a study with CHL1 knockout mice showed greater functional recovery after spinal cord injury (SCI) in its absence. We investigated CHL1 expression from 1 to

Quantitative western blot analysis in laminectomy control spinal cords of adult rats was used to provide the first report of the normal expression patterns of the N1, C1, C2 and C2' cassettes in the cervical, thoracic and lumbar regions of the spinal

NG2+ cells in the adult rat spinal cord proliferate after spinal cord injury (SCI) and are postulated to differentiate into mature glia to replace some of those lost to injury. To further study these putative endogenous precursors, tissue at 3 days a

Studies in the rat have shown that contusive spinal cord injury (SCI) results in devastating pathology, including significant loss of mature oligodendrocytes and astrocytes even in spared white matter. Subsequently, there is increased proliferation o

Following contusive spinal cord injury (SCI), 50% of oligodendrocytes in the residual white matter are lost within 24 h. NG2-expressing cell proliferation is maximal 3 days after SCI, and may be the source of mature oligodendrocytes and astrocytes th

Young rats display an accelerated rate of locomotor recovery after contusive spinal cord injury (SCI) compared to adults subjected to a similar standardized injury. We examined possible differences in the responses to SCI at the injury site and in th

After spinal cord injury (SCI), about 50% of the oligodendrocytes and astrocytes in the residual white matter at the injury site are lost by 24 h. However, chronically after SCI, the density of oligodendrocytes is normal. Previous studies have shown
