RBFOX3 and Gliosis: In miR-127 group, the NeuN-positive cell counts (Fig. 3d) and the mean densities of CGRP (Fig. 3h) and GAP-43 (Fig. 3l) were significantly decreased compared with the NS-miRNA group (Fig. 3c,g,k, P < 0.05), whereas no difference in gliosis was detected in miR-127 group (versus NS-miRNA group, P > 0.05) (Fig. S2c,d).
