↵^aGroup designations: Sham, sham-operated (laminectomy only) animals; PBS, injured animals with PBS injection (control for NSC transplantation); SCI, animals with injury alone; TP, animals that received NSC TP at 1 week after injury; TMT, animals with TMT alone (PBS injection without TP); SCI with TMT, injured animals with TMT alone; TP + TMT, animals with a combination of TP + TMT. See the Materials and Methods for detailed group designations. Numbers in parentheses indicate the subtotal number of animals in each group.
↵^bTime point refers to the duration elapsed after injury.
↵^cELISA (SCS), ELISA experiment measuring levels of BDNF, NT-3, and IGF-1 in serum, CSF, and spinal cord parenchyma (epicenter); ELISA (SEC) ELISA experiment measuring levels of BDNF, NT-3, and GDNF in the spinal cord tissue at the epicenter and caudal regions.
