Abstract

Female Sprague-Dawley rats were used as models of moderate contusion spinal cord injury to evaluate the efficiency of single systemic (intravenous) infusion of human mononuclear cord blood cells for restoration of the motor function of hind limbs. The dynamics of recovery of hind limb motor function was assessed using a specially designed method based on calculation of selective dispersion and amplitude-dependent dispersion of hind limbs joint angles measured in the swimming test. The obtained data suggest that systemic application of human mononuclear cord blood cells significantly (p<0.05) promoted recovery of hind limb motor function in the animal models of contusion spinal cord injury of moderate severity in comparison with control animals (without cell therapy).
