Therapeutic effect of umbilical cord blood cells on spinal cord injury

Spinal cord injury (SCI) is a nervous system disease characterized by sensory and motor dysfunction, axonal apoptosis, decreased vascular density, inflammation. At present, surgical treatment, drug cell therapy can be used. Surgical treatment improve independent function scores, promote the recovery of neurons in spinal cord, but only symptoms. Complete SCI has not yet been achieved. However, differentiation stem cells brings hope for SCI. Umbilical blood (UCBs) are ethically readily available repair neuronal damage. it still unclear how they symptoms nerve severity. In this paper, role UCBs described detail from different aspects such as behavior, morphology, molecular expression changes, so to provide new ideas theoretical directions future research.
