RESUMEN
Stem cells play important role in the development and in the maintenance of specific tissues. They have been identified in majority of the organs like liver, blood, skin and intestine. Role of stem cells in regenerative medicine have been implicated in many chronic diseases. Stem cell research is a new opportunity to those patients whose organs are damaged or diseased. The discovery of stem cells in central and peripheral nervous system is relatively recent. Spinal cord injury is one of the major neurological disaster affecting mostly young lives. Stem cell transplantation in spinal cord injury patients have shown encouraging results. Different sources of stem cells are being exploited for spinal cord injury as well as other neurological disorders.
