Figure Lengend Snippet: SSCs alleviate the radiation-induced bone injury in mice. (A–G) Micro-CT analysis of bone microstructure. (A) Representative micro-CT images of femurs. Quantitative analysis of (B) bone mineral density (BMD), (C) bone volume fraction (BV/TV), (D) trabecular thickness (Tb.Th), (E) trabecular number (Tb.N), (F) connectivity density (Conn.D), and (G) trabecular separation (Tb.Sp) at 2- and 4-weeks post irradiation. (H–K) Histological analysis (Scale bar: 100 μm). (H) H&E staining showing steatosis (arrows) and (I) quantitative analysis of steatotic lesions per field. (J) TRAP staining showing osteoclasts (arrows) and (K) quantitative analysis of osteoclast number per field. (L–O) Immunohistochemical staining of osteogenic markers (Scale bar: 100 μm). (L) Osterix staining and (M) quantitative analysis of Osterix-positive area. (N) β-catenin staining and (O) quantitative analysis of β-catenin-positive area. All experiments were conducted in three groups: Control, irradiation (IR), and IR plus SSC (IR+SSC) at 2- and 4-weeks post-irradiation. All data are presented as mean ± SD, with statistical significance determined by unpaired two-tailed Student’s t-test (* p < 0.05; ** p < 0.01; *** p < 0.001)

Article Snippet: Paraffin sections of femurs were dewaxed to water, and TRAP staining was performed using a TRAP staining kit (Servicebio, Wuhan, China, G1050-50T) according to the manufacturer’s instructions.

(A) The timeline demonstrated the experimental procedures. (B) The micro-CT scanning results. (C) Representative images of H&E staining (the black scale bars and white scale bars are 200 and 100 μm, respectively). (D) Representative images of Masson trichrome staining (the black scale bars and white scale bars are 200 and 100 μm, respectively). (E) Cementoenamel junction (CEJ)–alveolar bone crest (ABC) distance. (F) bone volume/total volume (BV/TV). (G) Loss of attachment in H&E staining. (H) Semiquantitative analysis of Masson trichrome staining. (I) Representative immunohistochemical images showing the expression level of inflammatory factor IL-6, IL-8, and IL-10, osteogenic factor COL1, and RUNX2, and TRAP staining showing the number of osteoclasts. Scale bar = 100 μm. (J) Quantitative analysis of IL-6-positive cells, IL-8-positive cells, IL-10-positive cells, COL1-positive cells, and RUNX2-positive cells. (K) Quantitative result of TRAP+ cells.
