  1. Animal Group Assignments. Female Long-Evans rat were divided among 9 groups. Using the indicated tracer, Fluorogold (FG) or Dextran Tetramethyl Rhodamine (DTMR), TPS neurons were prelabelled by a series of bilateral injections into the upper lumbrosacral enlargement. Allowing 1-week for tracer transport, animals in groups 4-8 were subjected to either a T9 complete spinal transection (Txn) or moderate spinal contusion injury (25 mm weight drop, NYU Impactor; Con). Following spinal cord injury, animals were allowed to recover for the indicated period of time. The final column of this table indicates the time point comparisons that were made for both the gene and PCR validation studies conducted during this study
