MenSCs embedded in collagen gel preserved the water content of degenerated disc following discectomy. (A): Midsagittal MR images (T2- weighted) of degenerated disc at 4 and 12 weeks after various treatment. Images are representative of seven replicates. (B) MR imaging index for each group. (C): Pfirrmann grading of disc degeneration after various treatment. Values are presented as mean ± SEM. * P < 0.05, ** P < 0.01, *** P < 0.001.
