Figure Lengend Snippet: Co-culture with SSCs rescues the function of irradiated osteogenic precursor cells. (A, B) Cell apoptosis was analyzed by flow cytometry with Annexin V-PE/7AAD double staining. (A) Representative flow cytometry plots. (B) Quantitative analysis of the apoptotic rate. (C, D) ALP activity was assessed. (C) Representative ALP staining images (Scale bar: 50 μm). (D) Quantitative analysis of the relative ALP activity. (E, F) Mineralization capacity was evaluated using Alizarin Red S staining. (E) Representative staining images of mineralized nodules (Scale bar: 100 μm). (F) Quantitative analysis of the relative mineralization level. (G, H) Cell migration was determined by a migration assay. (G) Representative images of migrated cells (Scale bar: 50 μm). (H) Quantitative analysis of the relative cell migration level. 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).

Article Snippet: After irradiation and corresponding interventions, cells were cultured in osteogenic induction medium (iXCells Biotechnologies, San Diego, CA, Cat. No. MD-0006) for 7 days.

Figure Lengend Snippet: SSCs exert rescue effects via the Wnt/β-catenin signaling pathway. (A) Representative ALP staining images of cells in each group (Scale bar: 50 μm). (B) Quantitative analysis of ALP activity in each group. (C) Representative Alizarin Red S staining images of cells in each group (Scale bar: 100 μm). (D) Quantitative analysis of Alizarin Red S staining in each group. (E) Relative mRNA expression levels of osteogenic marker genes ( Runx2 , Col1a1 , and OCN ) detected by qRT-PCR. GAPDH was used as an internal reference gene. (F) Representative Western blot images showing the expression levels of RUNX2, COL1A1, OCN, and β-catenin in each group. GAPDH was used as a loading control. (G) Quantitative analysis of Western blot results (gray value ratio of target protein to GAPDH) in each group.
