Summary
This chapter summarizes pioneering work on neural tissue transplantation that showed the feasibility of cell replacement as a treatment for spinal cord injury (SCI). It focuses on neural transplants with emphasis on the potential for neural stem cells (NSCs) and lineage-restricted precursors to replace damaged neurons and glia and to enhance regeneration. NSC has been identified not only in the fetal central nervous system (CNS), but also at later stages of CNS development and in select regions of the brain and spinal cord throughout adult life. The chapter present results of their transplantation into the spinal cord with respect to issues of fate, potential therapeutic properties and problems that need to be solved. It considers strategies for activating endogenous stem cells in the adult spinal cord for repair. Finally, the chapter reviews experimental strategies for cellular replacement in traumatic injury.

Multiple classes of precursor cells have been isolated and characterized from the developing spinal cord including multipotent neuroepithelial (NEP) stem cells and lineage-restricted precursors for neurons (NRPs) and glia (GRPs). We have compared the survival, differentiation and integration of multipotent NEP cells with lineage-restricted NRPs and GRPs using cells isolated from transgenic rats that express the human placental alkaline phosphatase gene. Our results demonstrate that grafted NEP cells survive poorly, with no cells observed 3 days after transplant in the adult hippocampus, striatum and spinal cord, indicating that most CNS regions are not compatible with transplants of multipotent cells derived from fetal CNS. By contrast, at 3 weeks and 5 weeks post-engraftment, lineage-restricted precursors showed selective migration along white-matter tracts and robust survival in all three CNS regions. The grafted precursors expressed the mature neuronal markers NeuN and MAP2, the astrocytic marker GFAP, the oligodendrocytic markers RIP, NG2 and Sox-10, and the synaptic marker synaptophysin. Similar behavior was observed when these precursors were transplanted into the injured spinal cord. Predifferentiated, multipotent NEP cells also survive and integrate, which indicates that lineage-restricted CNS precursors are well suited for transplantation into the adult CNS and provide a promising cellular replacement candidate.

Microtubules are important for the growth and maintenance of stable neuronal processes and their organisation is controlled partly by microtubule-associated proteins (MAPs). MAP 1B is the first MAP to be expressed in neurons and plays an important role in neurite outgrowth. MAP 1B is phosphorylated at multiple sites and it is believed that the function of the protein is regulated by its phosphorylation state. We have shown that the monoclonal antibody (mAb) RT97, which recognises phosphorylated epitopes on neurofilament proteins, fetal tau, and on Alzheimer's paired helical filament-tau, also recognises a developmentally regulated phosphorylation epitope on MAP 1B. In the rat cerebellum, Western blot analysis shows that mAb RT97 recognises the upper band of the MAP 1B doublet and that the amount of this epitope peaks very early postnatally and decreases with increasing age so that it is absent in the adult, despite the continued expression of MAP 1B in the adult. We confirmed that mAb RT97 binds to MAP 1B by showing that it recognises MAP 1B immunoprecipitated from postnatal rat cerebellum using polyclonal antibodies to recombinant MAP 1B proteins. We established that the RT97 epitope on MAP 1B is phosphorylated by showing that antibody binding was abolished by alkaline phosphatase treatment of immunoblots. Epitope mapping experiments suggest that the mAb RT97 site on MAP 1B is near the N-terminus of the molecule. Despite our immunoblotting data, immunostaining of sections of postnatal rat cerebellum with mAb RT97 shows a staining pattern typical of neurofilaments with no apparent staining of MAP 1B. For instance, basket cell axons and axons in the granule cell layer and white matter stained, whereas parallel fibres did not. These results suggest that the MAP 1B epitope is masked or lost under the immunocytochemical conditions in which the cerebellar sections are prepared. The upper band of the MAP 1B doublet is believed to be predominantly phosphorylated by proline-directed protein kinases (PDPKs). PDPKs are also good candidates for phosphorylating neurofilament proteins and tau and therefore we postulate that the sites recognised by RT97 on these neuronal cytoskeletal proteins may be phosphorylated by similar kinases. Important goals are to determine the precise location of the RT97 epitope on MAP 1B and the kinase responsible.
