Transplantation of human umbilical cord blood mononuclear cells into the injured site of spinal cord did not affect the lesion extension. The survival time of transplanted cells in the injured area was 6 weeks after treatment. The transplanted group indicated better functional recovery than the untreated ones (Rodrigues et al., 2012). There is sufficient evidence which prove that stem cell therapy could be effective in spinal cord injuries but a strategy to potentiate this stem cell transplantation results is required (Niapour et al., 2012; Chhabra and Sarda, 2015).
