AbstractSpinal cord injury results in irreversible tissue damage followed by a very limited recovery of function. In this study we investigated whether transplantation of undifferentiated human induced pluripotent stem cells (hiPSCs) into the injured rat spinal cord is able to induce morphological and functional improvement. hiPSCs were grafted intraspinally or intravenously one week after a thoracic (T11) spinal cord contusion injury performed in Fischer 344 rats. Grafted animals showed significantly better functional recovery than the control rats which received only contusion injury. Morphologically, the contusion cavity was significantly smaller, and the amount of spared tissue was significantly greater in grafted animals than in controls. Retrograde tracing studies showed a statistically significant increase in the number of FB-labeled neurons in different segments of the spinal cord, the brainstem and the sensorimotor cortex. The extent of functional improvement was inversely related to the amount of chondroitin-sulphate around the cavity and the astrocytic and microglial reactions in the injured segment. The grafts produced GDNF, IL-10 and MIP1-alpha for at least one week. These data suggest that grafted undifferentiated hiPSCs are able to induce morphological and functional recovery after spinal cord contusion injury.

Object. Human neuroteratocarcinoma (hNT)—derived neurons are differentiated postmitotic neurons derived from a human teratocarcinoma cell line following treatment with retinoic acid. In preclinical transplantation studies investigators have demonstrated both their safety as a source of neurons for transplantation and efficacy in treating stroke-related behavioral deficits. The objective of this study was to examine whether hNT neurons transplanted in an area of complete spinal cord contusion would improve electrophysiological measures of spinal cord function. Methods. Complete spinal cord contusion injury, defined as the complete loss of motor evoked potentials (MEPs), was produced in 30 rats at T-8. Ten rats with contused spinal cords underwent transplantation with hNT neurons within the site of contusion immediately after injury (immediate transplant group). Ten rats underwent hNT neuron transplantation following a 2-week evaluation for loss of MEPs (delayed transplant group). Ten other rats with contusion injury served as a spinal cord injury control group, and 10 rats underwent only a T-8 laminectomy and served as noninjured controls. All rats survived 8 weeks after transplantation. In the delayed transplant group significant functional recovery was observed, as demonstrated by return of MEPs and a modest improvement of motor function. Immunohistochemical analysis showed the survival, integration, and long fiber outgrowth of the grafted hNT neurons. Conclusions. These findings suggest that the transplantation of the hNT neurons may be an effective means of reestablishing electrical connectivity of the injured spinal cord.
