Figure 5. TFAM might regulate gene transcription of IGF1 and effected alterations in the function recovery of rats after SCI. (A) IGF1 and TFAM was significantly down-regulated after SCI. (B) BBB scale was performed for assessing motor recovery of rats hind limbs after SCI. (C) Gait footprints were recorded at 35 days post-injection and there were significant improvement in the TFAM-overexpression group in average speed and cadence (steps/second) compared with SCI group.
