Transplantation of Adult Rat Schwann Cells into the Injured Spinal Cord.

Adult Schwann cells (SCs) can provide both a permissive substrate for axonal growth and a source of cells to ensheath and myelinate axons when transplanted into the injured spinal cord. Multiple studies have demonstrated that SC transplants can be used as part of a combinatorial approach to repairing the injured spinal cord. Here, we describe the protocols for collection and transplantation of adult rat primary SCs into the injured spinal cord. Protocols are included for the tissue culture procedures necessary for collection, quantification, and suspension of the cells for transplantation and for the surgical procedures for spinal cord injury at thoracic level nine (T9), reexposure of the injury site for delayed transplantation, and injection of the cells into the spinal cord.
