MRI and histological analyses. A Representative T2-weighted magnetic resonance imaging (MRI) of the coccygeal discs: normal and damaged (sagittal view, yellow circle). B MRI index for discs of each group. Scale bars: coronal 5 mm, axial 1 mm. C Representative images of hematoxylin and eosin (H&E) and Safranin O staining. H&E disc nucleus pulpous (NP) area and cell number. D Histological score analysis from Safranin O staining. E Quantitative analysis of H&E revealed the highest preservation of disc structure in G4. F The highest disc cell number is revealed in normal disc followed by G4. Mean ± SD (n = 8), one-way ANOVA, scale bars: 500 μm, 50 μm
