Injectable Hydrogel Combined with Nucleus Pulposus-Derived Mesenchymal Stem Cells for the Treatment of Degenerative Intervertebral Disc in Rats
Typical radiographs and DHI% of different groups preoperation, preinjection, and 1, 2, 4, and 8 weeks after injection. (a) The radiographs of different groups. (b) DHI% was applied to quantitatively evaluate the changes of disc height. The H-gel+cell group is the hydrogel+cell group. All data are expressed as the ; 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.
