a Representative immunofluorescent images of F4/80 (red) staining and DAPI (blue) staining of nuclei in the caudal endplates of L4/5 in 20-month-old mice with clodronate liposomes (CL) or vehicle injection. Scale bars, 50 μm. bi All the experiments were conducted in 20-month-old mice or 3-month-old mice with CL or vehicle injection. b Representative images of immunofluorescent analysis of CD31 (green), Emcn (red) staining and DAPI (blue) staining of nuclei in the endplates. Scale bars, 50 μm. c Permillage of CD31+Emcn+ area in the endplates of b. d Representative µCT images of the caudal endplates of L4/5 (coronal view). Scale bars, 500 μm. e Quantitative analysis of the total porosity of d. f Representative images of safranin O and fast green staining of the endplates. Scale bars, 50 μm. g Endplate scores of f. h Representative images of immunohistochemical staining of Osterix (Osx) in the endplates. Scale bars, 50 μm. i Quantitative analysis of the number of Osx+ cells in endplates of h. n = 6 per group. Data are represented as means ± standard deviations, as determined by One-way ANOVA.
