MRI images and MRI index of different groups. (a) Typical T2-weighted MRI images of different groups preoperation, preinjection, and 1, 2, 4, and 8 weeks after injection. (b) The MRI index was applied to quantitatively evaluate the rehydration and regeneration of degenerative disc. The H-gel+cell group is the hydrogel+cell group. All data are expressed as the mean ± SD; the error bars represent the standard deviation of measurements for 6 separate samples (n = 6); ∗p < 0.05, ∗∗p < 0.01 compared with control group; #p < 0.05, ##p < 0.01 compared with hydrogel+cell group; &p < 0.05, &&p < 0.01 compared with cell group.
