In the article “Implantation of hyaluronic acid hydrogel prevents the pain phenotype in a rat model of intervertebral disc injury,,” in Fig. 5D, i, the image of AF c-fos staining for HA hydrogel was erroneously a duplicate of AF c-fos staining for the Sham group. The figure now displays the correct image. In the same figure, the arrow in AF c-fos staining for the injury group initially indicated the wrong protein. The arrow was repositioned to indicate the correct protein. The HTML and PDF versions of the paper have been corrected.
