Differential expression of neuropsin and protease M/neurosin in oligodendrocytes after injury to the spinal cord.

abstract：:Previous studies suggest that glial cells contribute to synaptogenesis in specific neurons from the postnatal CNS. Here, we studied whether this is true for Purkinje cells (PCs), which represent a unique neuronal cell type due to their large size, massive synaptic input, and high vulnerability. Using new glia-free cul...
