Abstract (original English)

Diseases of the central nervous system still remain among the most challenging pathologies known to mankind, having no or limited therapeutic possibilities and a very pessimistic prognosis. Advances in stem cell biology in the last decade have shown that stem cells might provide an inexhaustible source of neurons and glia as well as exerting a neuroprotective effect on the host tissue, thus opening new horizons for tissue engineering and regenerative medicine. Here, we discuss the progress made in the cell-based therapy of spinal cord injury. An emphasis has been placed on the application of adult mesenchymal stromal cells (MSCs). We then review the latest and most significant results from in vitro and in vivo research focusing on the regenerative/neuroprotective properties of MSCs. We also attempt to correlate the effect of MSCs with the pathological events that are taking place in the nervous tissue after SCI. Finally, we discuss the results from preclinical and clinical trials involving different routes of MSC application into patients with neurological disorders of the spinal cord.
