Macroscopic observation and histological score of different groups. (a) Macroscopic images of different groups at 8 weeks after injection. (b) The relative area of nucleus pulposus at 8 weeks after injection. (c) Histological scores obtained at 8 weeks after injection. The H-gel+cell group is the hydrogel+cell group. Data represent ; the error bars represent the standard deviation of measurements for 6 separate samples (); , compared with control group; , compared with hydrogel+cell group; , compared with cell group.
