Impairment in motor and sensory function following spinal cord injury (SCI) has been attributed to disruption of descending motor pathways and ascending sensory ones.After SCI, very little regenerative response occurs in the adult mammalian central nervous system (CNS), leading to permanent loss of function and paralysis. There is no available therapy for restoration of function at present. Many investigators have researched strategies for the restoration of function resulting from SCI, and cellular transplantation has emerged as a promising strategy.
