Title

Co-transplantation of Human Embryonic Stem Cell-derived Neural Progenitors and Schwann Cells in a Rat Spinal Cord Contusion Injury Model Elicits a Distinct Neurogenesis and Functional Recovery

English Abstract

Co-transplantation of neural progenitors (NPs) with Schwann cells(SCs) might be a way to overcome low rate of neuronal differentiation of NPs following transplantation in spinal cord injury(SCI) and the improvement of locomotor recovery. In this study, we initially generated NPs from human embryonic stem cells(hESCs) and investigated their potential for neuronal differentiation and functional recovery when co-cultured with SCs in vitro and cotransplanted in a rat acute model of contused SCI. Co-cultivation results revealed that the presence of SCs provided a consistent status for hESC-NPs and recharged their neural differentiation toward a predominantly neuronal fate. Following transplantation, a significant functional recovery was observed in all engrafted groups (NPs, SCs, NPs+SCs) relative to the vehicle and control groups. We also observed that animals receiving co-transplants instituted a better state as assessed with the BBB functional test. Immunohistofluorescence evaluation five weeks after transplantation showed invigorated neuronal differentiation and limited proliferation in the co-transplanted group when compared to the individual hESC-NPs grafted group. These findings have demonstrated that the co-transplantation of SCs with hESC-NPs could offer a synergistic effect, promoting neuronal differentiation and functional recovery.
